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-XH68-HFP5-5X5M daphne: WebSocket handshake header smuggling through autobahn splitlines() mishandling of non-standard line separators

daphne before 4.2.2 reconstructs a raw HTTP request from Twisted's parsed headers and feeds it to autobahn for WebSocket handshake processing. Twisted does not treat \x0b, \x0c, \x1c, \x1d, \x1e, or \x85 as header line separators, but autobahn decodes header values to str and calls splitlines. An...

Directory Traversal

Overview Affected versions of this package are vulnerable to Directory Traversal in the processing of uploaded filenames containing Windows-style path separators. An attacker can write arbitrary files outside the intended extraction directory on Windows systems by crafting a malicious filename in...

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...

samba: Fix of 2 CVEs

CVE-2019-3880: Refuse winreg SaveKey/RestoreKey RPCs to prevent writing registry hive files outside intended share boundaries via symlink races - CVE-2019-10218: Reject server-supplied filenames containing path separators in SMB1 directory listings to protect libsmbclient consumers from path...

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...

WS-2017-0136

Strings containing regex special characters cannot be used as interpolation format separators, as they are regex escaped, even though the separator is not used as a regex...

Unity Linux 20.1070e Security Update: expat (UTSA-2026-017379)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-017379 advisory. xmlparse.c in Expat aka libexpat before 2.4.5 allows attackers to insert namespace-separator characters into namespace URIs. Tenable has extracted the preceding...

SUSE CVE-2026-6321

fast-uri decoded percent-encoded path separators and dot segments before applying dot-segment removal in its normalize and equal functions. Encoded path data was treated like real slashes and parent-directory references, so distinct URIs could collapse onto the same normalized path. Applications...

CVE-2026-6321

A flaw was found in fast-uri. A remote attacker could exploit this vulnerability by providing a specially crafted Uniform Resource Locator URL containing percent-encoded path separators and dot segments. Due to incorrect processing, fast-uri would decode these elements before proper normalization...

fast-uri 安全漏洞

fast-uri is an open-source, dependency-free RFC 3986 URI parser and toolkit developed by Fastify. Versions of fast-uri 3.1.1 and earlier contained security vulnerabilities. These vulnerabilities stemmed from the normalize function decoding percent-encoded permission separators within the host...

PT-2026-36996

Name of the Vulnerable Software and Affected Versions fast-uri versions prior to 3.1.2 Description The normalize function decoded percent-encoded authority delimiters within the host component and re-emitted them as raw delimiters during serialization. This allows a host combining an allowed...
