devalue: Malformed null-prototype object keys bypass __proto__ rejection via property-key coercion

This is another instance of https://github.com/sveltejs/devalue/security/advisories/GHSA-mwv9-gp5h-frr4, where some payloads could cause parse to create objects with a proto own property. This on its own is not enough to cause prototype pollution, and indeed this is actually how JSON.parse works,...

virtualenv bash and fish activation scripts execute commands embedded in paths

Impact The generated activate bash/zsh and activate.fish scripts interpolate a shlex.quote-ed value into a position that quotes it a second time. The extra quotes terminate the quoted run early and leave part of the value parsed as shell code, so a path containing shell metacharacters runs comman...

virtualenv: Command injection via --prompt in activate.bat (batch activator)

BatchActivator.quote returned its input unchanged, the only activator with no escaping at all. --prompt, the VIRTUALENVPROMPT environment variable, and the config file all set the prompt, and activate.bat writes it straight into @set "VAR=value". A prompt containing a double quote closes that...

piscina: Prototype-pollution gadget in ThreadPool.options allows RCE via execArgv / loadBalancer / env

Summary A prototype-pollution gadget in ThreadPool.options allows an attacker who can pollute Object.prototype to execute arbitrary code in Piscina worker threads, invoke arbitrary functions during task scheduling, or inject environment variables into workers. The root cause is that...

basic-ftp: Quadratic-time CPU denial of service in Client.list() Unix directory-listing parser (RE_LINE backtracking)

Summary Client.list parses the server's directory listing with the Unix-style parser in parseListUnix.js. Its RELINE regex has two adjacent \S+?:\s\S+ groups owner name, then group name followed by a required numeric size group. When a line starts with a valid listing prefix but the tokens after ...

SiYuan discloses an administrator's open documents and search terms to anonymous readers

Summary /api/system/getConf serves Conf.UILayout to publish readers after passing it through FilterConfByPublishIgnore, whose only function is to filter that layout. The layout is written exclusively by setUILayout, which is administrator-gated, so what readers receive is the administrator's own...

SiYuan: Unauthenticated SQL injection in searchDocs via unescaped keyword (publish mode): cross-notebook read/write with statement stacking

Summary The /api/filetree/searchDocs endpoint concatenates the caller-supplied search keyword directly into a SQL statement with no escaping and no parameter binding. The endpoint is gated by CheckAuth only reachable by the publish RoleReader token, and by the anonymous account when...

virtualenv: Downloaded seed wheels (pip/setuptools) are not integrity-checked before use

downloadwheel runs pip download and hands the result straight to the seeder, with nothing checking the bytes it gets back. The embedded pip and setuptools wheels carry a BUNDLESHA256 that virtualenv checks on every load, but a wheel fetched over the network for the periodic-update feature or the...

virtualenv writes prompt values into pyvenv.cfg without sanitizing line boundaries, allowing configuration injection

Summary pyvenv.cfg is a line-based format with no escape syntax. PyEnvCfg.write wrote values verbatim, while PyEnvCfg.readvalues parses the file with str.splitlines. A value containing a line boundary therefore became additional configuration lines, and because reading is last-wins, the injected...

fastify vulnerable to Denial of Service via unhandled exception on HTTP/2 trailer responses

Impact fastify crashes with an uncaught ERRHTTP2INVALIDCONNECTIONHEADERS exception when a route that registers a response trailer via reply.trailer is served over HTTP/2. Fastify unconditionally adds the Transfer-Encoding: chunked header when a trailer is set, which is forbidden on HTTP/2, so...

PyJWT.decode() reintroduces options-dict mutation, enabling silent claim-verification bypass on dict reuse

Summary PyJWT.decode/decodecomplete mutates a caller-supplied options dict in place whenever verifysignature is falsy, adding verifyexp/verifynbf/verifyiat/verifyaud/verifyiss/verifysub/verifyjti keys directly onto that object. If application code reuses the same options dict across calls a confi...

Tornado: Unbounded query-string argument count allows event-loop-stalling DoS

Summary HTTPServerRequest.init in tornado/httputil.py parses the URL query string via parseqsbytes with no field-count limit — while the sibling POST-body parsing path parsebodyarguments received a maxnumfields=1000 cap added earlier in this exact same release v6.5.8, commit 8d6363ed, explicitly ...

tornado: CurlAsyncHTTPClient enforces no response-size limit — decompression bomb drives unbounded memory accumulation to OOM

An unbounded memory accumulation decompression bomb in tornado.curlhttpclient.CurlAsyncHTTPClient — the client-side sibling gap of CVE-2026-49855 — verified end-to-end on the 2026-08-15 master snapshot 6.6.dev1 and present unchanged in the latest release tag v6.5.8 and on master checked 2026-08-1...

Tornado: StaticFileHandler follows symlinks outside static root (path traversal)

Summary StaticFileHandler allows an unauthenticated attacker to read arbitrary files from the server's filesystem by requesting a path that resolves to a symbolic link placed inside the static root directory. Any application that serves user-uploadable content, or whose static directory is...

GitPython submodule update path traversal can write outside the repository

Affected: GitPython 3.1.61 latest release and main — git/objects/submodule/base.py. git diff 3.1.61 origin/main -- git/objects/submodule/ is empty, so both are identical here. --- The gap The fix for GHSA-hmq2-w58f-27jc added Submodule.validatedname and wired it into update and five siblings,...

hono/jsx renders plain strings unescaped in boundary components, leading to XSS

Summary hono/jsx does not HTML-escape a plain string placed directly as a child or fallback of Suspense or ErrorBoundary, as the only child of a Context.Provider, or as the root value of renderToString / renderToReadableStream from hono/jsx/dom/server. Such a string is emitted as markup instead o...

fastify vulnerable to request body replacement via an async validation result collision

Impact Fastify runs a route's validator and, for a result shaped like value, error , unwraps it: an error becomes a validation failure and value replaces the request part. This convention is intended for synchronous custom compilers for example Joi. A JSON Schema $async validator, however, resolv...

fastify vulnerable to authentication bypass via malformed URLs reaching encapsulated not-found handlers

Impact Fastify routes a malformed URL under one plugin prefix to the custom not-found handler of a different sibling plugin, invoking the handler registered last and skipping the preHandler declared in its setNotFoundHandler. When the request method has no route in the main router, a malformed...

fastify vulnerable to request validation bypass via skipped boolean false schemas

Impact Fastify decided whether to validate a request part by checking its schema for JavaScript truthiness. JSON Schema Draft 7 defines the boolean false as a valid schema that rejects every instance, but because false is falsy, a route that set body, querystring, params, or headers to false had...

fastify vulnerable to header validation bypass via incomplete schema case normalization

Impact Fastify lowercases header-schema property names before compiling the schema, because Node.js stores request header names in lowercase. That normalization was incomplete: it lowercased only top-level properties keys and the root required array, and did not lowercase the JSON Schema Draft 7...
