Banks: Path traversal in `DirectoryPromptRegistry.set()` allows arbitrary file write outside the registry root

Summary DirectoryPromptRegistry.set interpolates the attacker-controllable Prompt.name into a Path expression with no canonicalization. An application that derives the prompt name from request data lets a caller write attacker-controlled bytes outside the configured registry directory. Details...

pypdf: Inefficient handling of non-whitespace inputs in read_until_whitespace

Impact An attacker who uses this vulnerability can craft a PDF which leads to long runtimes. This requires a call to readuntilwhitespace with an input which does not have whitespace for a long time. Patches This has been fixed in pypdf==6.15.0. Workarounds If you cannot upgrade yet, consider...

elFinder: ZIP extraction bypasses uploadDeny MIME filter allowing PHP file upload (RCE)

Summary elFinder provides uploadDeny and uploadAllow options in its connector configuration to restrict which MIME types may be uploaded. When uploadDeny includes text/x-php, direct upload of .php, .phtml, and .phar files is correctly blocked. However, the extract command ZIP decompression...

elFinder: CSRF in netmount allows forced FTP mounts and server-side FTP connections

Summary The PHP connector's CSRF gate protects many mutating commands, but it does not protect the netmount connector command. In the shipped minimal connector setup, FTP network mounting is enabled by default, so a cross-site request can force an elFinder instance to mount an attacker-chosen FTP...

pnpm: Virtual store linker path traversal via unvalidated depPath name in lockfileToDepGraph

Summary The virtual store linker constructs package installation directories using path.joinmodules, pkgName where pkgName is extracted from lockfile packages keys via dp.parsedepPath.name without validation. A crafted pnpm-lock.yaml with traversal sequences in depPath keys e.g.,...

pnpm: A tarball dependency's manifest `name` escapes node_modules → arbitrary file write/overwrite on install

Summary When resolving a package, pnpm uses the resolved manifest name as a raw path segment for the isolated-linker import target. A tarball dependency whose package.json name is a scoped path traversal @x/../../…/ is therefore extracted outside nodemodules, to an attacker-chosen absolute path,...

NLTK: Quadratic-time DoS in PorterStemmer via long runs of 'y'

nltk.stem.PorterStemmer.stem -- a ubiquitous public API applied to arbitrary, often untrusted, tokens -- runs in On^2 time on a token containing a long run of the letter 'y', letting a single 20-50 KB token pin a CPU core CWE-407. Root cause isconsonantword, i was made iterative commit for 3633,...

NLTK: Downloader.download follows hardlinks and overwrites outside-root files

Summary NLTK's downloader now blocks symlink escapes during ZIP extraction, but it still treats pre-existing hardlinks inside the install tree as ordinary in-root files. A normal package install can therefore overwrite an outside-root inode through that hardlink. Details - Vulnerability type:...

NLTK: Model-artifact APIs bypass pathsec and touch files outside allowed roots

Summary Several model-artifact APIs still treat caller-controlled model paths as ordinary filenames even when NLTK path security is enforced. The same outside-root paths are rejected by guarded helpers, but these public read and write flows still use raw file APIs. Details - Vulnerability type:...

NLTK: Quadratic CPU Exhaustion in `XMLCorpusView._read_xml_fragment()`

Summary XMLCorpusView.readxmlfragment reads a corpus file in 1 KiB blocks, appending each block to a growing fragment string, then calls VALIDXMLRE.matchfragment on the full accumulated buffer every iteration. Because each iteration rescans the entire accumulated fragment, the total amount of wor...

NLTK: Uncontrolled resource consumption in RecursiveDescentParser via ambiguous or left-recursive grammars

nltk.parse.RecursiveDescentParser and SteppingRecursiveDescentParser enumerate parses top-down with no bound on the number of recursive steps. A small, crafted context-free grammar makes a short input consume unbounded CPU and/or exhaust the Python recursion stack, pinning a process indefinitely ...

NLTK: Uncontrolled recursion in nltk.featstruct.FeatStructReader causes unhandled RecursionError (DoS) via deeply nested feature-structure input

Summary nltk.featstruct.FeatStructReader used by FeatStructstr and by FeatureGrammar.fromstring parses feature-structure strings such as a=1 with a recursive-descent parser that has no nesting-depth limit. A small, trivially-crafted input 700 bytes with deeply nested brackets drives the parser pa...

ImageMagick: Memory Leak when providing invalid options to the cli

A memory leak is possible when invalid options are passed to the cli magick...

humanfs: Recursive copy follows symlinked files and copies data from outside the source tree

Summary @humanfs/node does not treat symlinks as a separate case during copy operations. A symlink placed inside an attacker-controlled source tree can make copyAll read and copy the contents of any file readable by the process, even when that file is outside the directory being copied. Details T...

Faker: helpers.fake exploitable into arbritary code execution

Summary faker.helpers.fake can be tricked into arbritary code execution. Details fakeEval.resolveProperty resolves properties on functions itself instead of resolving the nested function first. This can be addressed by recursively calling resolveProperty instead of accessing the property after on...

Siyuan: Authenticated path traversal in /snippets/ static handler (serveSnippets) leaks conf/conf.json secrets and siyuan.db

Reporter: Cavan Loughran, Celvex Group Inc. Summary ------- The /snippets/filepath route handler serveSnippets in kernel/server/serve.go performs a bare filepath.Joinutil.SnippetsPath, filePath on the single-decoded c.Request.URL.Path and serves the result with c.File, with NO IsSubPath containme...

SiYuan: SQL Query in Block Search Exposes Hidden Published Document Content

Summary Siyuan's block search endpoint concatenates attacker-controlled paths values into SQL predicates used by non-SQL search modes. Through Siyuan's publish service, an unauthenticated visitor is forwarded to the kernel with a reader-role token and can reach POST /api/search/fullTextSearchBloc...

Apache Spark History Server allows stored cross-site scripting through unescaped application names

There is a lack of XSS escaping in the Spark History Server prior to 3.5.8 which allows a malicious Spark job to generate arbitrary unescaped frontend code which could lead to a minimal privilege escalation in browser. Users are encouraged to upgrade to Spark 3.5.8 or later. This CVE is marked as...

gRPC-Go: Heap Memory Exhaustion (OOM) via HTTP/2 DATA Frame Fragmentation

Impact An unauthenticated remote attacker can initiate a gRPC stream and purposefully fragment their payload into millions of tiny e.g., 1-byte HTTP/2 DATA frames. Even if the total payload volume falls within the configured connection and stream flow-control windows, each independent fragment...

TYPO3 CMS - Broken Access Control in Backend and Install Tool

Problem The referrer enforcement introduced with TYPO3-CORE-SA-2020-006 CVE-2020-11069 became ineffective in TYPO3 v13.0, where TYPO3 CMS started serving the backend and Admin Tool applications from the site's main entry script instead of the dedicated typo3/ directory. Whether a request originat...

Filament: Multi-factor authentication (app) codes can still be used after a newer code has been used

A flaw in the handling of one-time codes for app-based multi-factor authentication allows a previously issued code to be used after a newer code has already been accepted. This issue does not affect email-based MFA. Submitting the exact same code twice was already prevented, but any other code...

Filament: Password validity disclosure for accounts denied panel access on login page

When multi-factor authentication is enabled, the login page presents the multi-factor challenge before evaluating canAccessPanel. For an account that canAccessPanel denies, submitting the correct password renders the challenge while an incorrect password returns the generic failure message,...

Filament: Multi-factor authentication (app) can be bypassed when recovery codes are enabled

A flaw in the challenge handling for app-based multi-factor authentication allows the second factor to be bypassed. This issue does not affect email-based MFA. It also only applies when recovery codes are enabled...

pypdf: Possible long runtimes/large memory usage when extracting XForm objects

Impact An attacker who uses this vulnerability can craft a PDF which leads to long runtimes and large memory consumption. This requires extracting the text of a page with lots of XForm objects, where some of them might be re-used. Patches This has been fixed in pypdf==6.16.1. Workarounds If you...

pypdf: Possible infinite loop for TreeObject.insert_child

Impact An attacker who uses this vulnerability can craft a PDF which leads to an infinite loop. This requires a usually writing code path where TreeObject.insertchild is involved. Patches This has been fixed in pypdf==6.16.0. Workarounds If you cannot upgrade yet, consider applying the changes fr...

sqlparse: Reindentation of tuple lists causes near-cap quadratic CPU consumption

Summary When SQL is formatted with reindentation enabled, ReindentFilter repeatedly rebuilds prefixes of the current statement to calculate token offsets. An attacker who controls SQL sent to this opt-in formatting path can supply a parenthesized tuple list that remains just below the...

ApostropheCMS: Stored XSS via SVG SMIL URI-list scheme-policy bypass

Summary When SVG animation is allowed, attributeName="href" makes values a list of URL destinations. sanitize-html accepts a list that starts with a safe fragment even when values is explicitly scheme-checked, allowing a later javascript: destination to execute when the sanitized link is activate...

NLTK: JVM argument injection bypass via per-call options in the NLTK Stanford wrappers (incomplete fix of CVE-2026-12841)

Vulnerability The fix for CVE-2026-12841 CWE-88, JVM argument injection added validatejavaoptions to block dangerous JVM flags such as -agentlib, -agentpath, -javaagent, -Xrunjdwp, and @argfile references. However, the validation is only applied when setting global options via configjava. The jav...

league/commonmark: Denial of service via distinctly-named attributes in the Attributes extension

Impact AttributesExtension ships with the library but must be explicitly registered on the Environment; it is not included in CommonMarkConverter, GithubFlavoredMarkdownConverter, or GithubFlavoredMarkdownExtension. Applications that do not register AttributesExtension are not affected by this...

NLTK: Uncontrolled search path when invoking the Graphviz 'dot' binary

Two NLTK sites executed the Graphviz dot program by bare name, so process creation resolved it via the search path — and on Windows via the current working directory — rather than a validated absolute location. An attacker who can place a file named dot where resolution looks the CWD on Windows, ...

league/commonmark: Denial of service in the SmartPunct and Attributes extensions

Impact Two first-party extensions contain quadratic parsing paths. Both ship with the library but must be explicitly registered on the Environment; neither is included in CommonMarkConverter, GithubFlavoredMarkdownConverter, or GithubFlavoredMarkdownExtension. Applications that do not register...

league/commonmark XSS: `on*` event-handler filter in `AttributesExtension` bypassed with a U+000C form feed

Summary The AttributesExtension documents a security guarantee: Note: Attributes starting with on e.g. onclick or onerror are capable of executing JavaScript code and are therefore never allowed by default. You must explicitly add them to the allow list if you want to use them. —...

league/commonmark: Denial of service via crafted code fences, reference links, and emphasis delimiters

Impact Affected versions of league/commonmark perform super-linear work on three independent parsing paths, all of which are reachable on a stock new CommonMarkConverter with default configuration and no extensions registered. Each trigger fits on a single line of input, so no complex Markdown...

tornado: multipart split() creates huge temp list before max_parts check -> memory amplification DoS (httputil.py:34)

Description Summary parsemultipartformdata httputil.py:34 calls data.splitb"--"+boundary+b"\r\n" before the maxparts check :35. A 600KB body with 100k parts creates a 100k-element transient list first, then rejects transient memory amplification each split element is a copy. Pre-auth HTTP DoS. Ro...

Tornado: Incomplete fix for CVE-2026-35536: cookie attribute injection re-opened via the legacy case-insensitive `**kwargs` path in `set_cookie`

Summary The CVE-2026-35536 fix added a validation loop that rejects \x00-\x20\x3b\x7f, but only for the hardcoded lowercase keys name/domain/path/samesite. The still-live deprecated kwargs path writes attacker-supplied attribute values straight into the Morsel with no validation, and because...

Django REST framework: Potential bypass of Django `DATA_UPLOAD_MAX_MEMORY_SIZE` when parsing oversized JSON and urlencoded request bodies via DRF `request.data`

Summary While investigating Django REST Framework's request parsing behavior, I identified that DRF's high-level request.data parsing appears to bypass Django's configured DATAUPLOADMAXMEMORYSIZE protection for application/json and application/x-www-form-urlencoded request bodies. In the tested...

Django REST framework: AdminRenderer may disclose GET-protected data when rendering invalid write requests

Summary AdminRenderer may disclose data that would normally be protected by GET permissions when rendering a 400 Bad Request response for an invalid write request. If a view allows POST or another write method but denies GET, an invalid request rendered through AdminRenderer can invoke the view's...

nanoid: Integer Overflow or Wraparound

Summary An integer overflow in nanoidsize permanently corrupts the process-wide CSPRNG pool, causing all subsequent ID generation to return the deterministic string "uuuuuuuuuuuuuuuuuuuuu". Any application that passes user-influenced values to the size parameter loses all randomness guarantees fo...

pnpm: Environment secrets exfiltrated via env-placeholder expansion in proxy settings read from an untrusted pnpm-workspace.yaml

Summary pnpm expands $VAR environment placeholders in the httpProxy / httpsProxy / noProxy settings read from a project's pnpm-workspace.yaml. Because a project manifest is repository-controlled, a malicious repository that a victim merely clones and runs pnpm install in can route all install...

pnpm: pacquet trust-lockfile install can create dependency symlinks outside the project

Summary A crafted lockfile alias could reach several install-time filesystem joins. With --trust-lockfile or a frozen lockfile, traversal segments could create links outside the intended project or nodemodules boundary. This patch validates dependency names and every virtual-store slot before...

Appium: Reflected XSS / arbitrary JS in @appium/base-driver /test/guinea-pig* routes

Summary Appium's base-driver mounts the built-in /test/guinea-pig, /test/guinea-pig-scrollable and /test/guinea-pig-app-banner routes unconditionally on every server. The handler reflects the throwError query param, the comments POST field, and the User-Agent request header into the returned HTML...

MLFLOW_ALLOW_PICKLE_DESERIALIZATION=False safety control bypassed by mlflow.statsmodels flavor — RCE via crafted model artifact
