CVE-2026-53538

A flaw was found in Python-Multipart, a tool used for processing web form data. A remote attacker could exploit a vulnerability where the software incorrectly interprets certain characters as separators in web form data. This difference in interpretation compared to standard web practices allows ...

nodejs: Node.js: Authentication bypass due to TLS hostname handling and unicode dot separator mismatch

A flaw was found in Node.js. This flaw involves a mismatch in how Node.js handles TLS Transport Layer Security hostnames and unicode dot separators during authentication. This mismatch can lead to a wildcard-depth authentication bypass. An attacker could exploit this to bypass intended security...

CVE-2026-54555

CVE-2026-54555 affects rtK prior to 0.42.2. The issue lies in the permission splitter, which failed to conservatively split or reject shell constructs Bash treats as command boundaries or nested execution. Consequently, a command starting with an allowed prefix (e.g., git) could conceal a second,...

CVE-2026-54555 rtk: Permission-gate bypass in rtk rewrite auto-allow via unsplit shell separators

rtk filters and compresses command outputs before they reach your LLM context. Prior to 0.42.2, the permission splitter did not conservatively split or reject several shell constructs that Bash treats as command execution boundaries or nested execution. As a result, a command beginning with an...

CVE-2026-53539

Python-Multipart is a streaming multipart parser for Python. Prior to 0.0.30, when parsing application/x-www-form-urlencoded bodies, QuerystringParser located the field separator with a two step lookup: it first scanned the entire remaining buffer for &, and only when no & existed anywhere ahead...

CVE-2026-54293

NLTK Natural Language Toolkit is a suite of open source Python modules, data sets, and tutorials supporting research and development in Natural Language Processing. Prior to 3.10.0-rc1, nltk.data.load in NLTK is vulnerable to path traversal via URL-encoded path separators and traversal segments...

CVE-2026-53539

CVE-2026-53539 (Python-Multipart) affects the Python-Multipart streaming multipart parser. Prior to 0.0.30, parsing application/x-www-form-urlencoded bodies used a two-step field separator lookup, causing an O(B^2) worst-case workload per chunk when semicolon is used as the separator and no amper...

Linux Distros Unpatched Vulnerability : CVE-2026-54293

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - NLTK Natural Language Toolkit is a suite of open source Python modules, data sets, and tutorials supporting research and development in Natural Language...

Path Equivalence

Overview Affected versions of this package are vulnerable to Path Equivalence in the pathWithoutMatrixParams of AbstractPathMatchingHttpSecurityPolicy via specially crafted HTTP requests containing encoded semicolons, slashes, or backslashes in the request path. An attacker can gain unauthorized...

python-multipart: Quadratic-time querystring parsing with semicolon separators causes CPU denial of service

Summary When parsing application/x-www-form-urlencoded bodies, QuerystringParser located the field separator with a two step lookup: it first scanned the entire remaining buffer for &, and only when no & existed anywhere ahead did it fall back to scanning for ;. For a body that uses ; as the...

CVE-2026-44546

A flaw was found in daphne. This vulnerability arises from a parser differential where daphne reconstructs HTTP requests from Twisted's headers, but Twisted and autobahn handle certain header line separators differently. An attacker can exploit this to inject additional headers into the ASGI...

CVE-2026-39844

NiceGUI is a Python-based UI framework. Prior to 3.10.0, Since PurePosixPath only recognizes forward slashes / as path separators, an attacker can bypass this sanitization on Windows by using backslashes \ in the upload filename. Applications that construct file paths using file.name a pattern...

GHSA-HWC4-GMRW-5222 Gotenberg has path traversal in zip entry name via Windows-style separators in upload filename

Summary filepath.Base on the Linux container does not strip backslashes , because \ is only a path separator on Windows. A multipart filename like ........\Windows\System32\evil.pdf survives Gotenberg's input sanitisation and lands verbatim as the zip entry name when a multi-output route...

Strengthening Polymorphic Prompt Assembling: Dynamic Separator Generation against Emerging Prompt Injection Attacks

Polymorphic Prompt Assembling PPA defends LLM agents against prompt injections by randomly selecting separator pairs from a fixed pool to isolate user input from system instructions. Although effective, static pool reuse exposes a blast-radius vulnerability: once a separator leaks, it can be...

shell-quote 安全漏洞

Shell-quote is a software package developed by Jordan Harband. It is used for parsing and quoting shell commands. Shell-quote has a security vulnerability. This vulnerability stems from the quote function not verifying the object token input and the operator model used in parse. As a result, line...
