CVE-2026-6321 fast-uri vulnerable to path traversal via percent-encoded dot segments

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...

JLSEC-2026-389

The curl URL parser wrongly accepts percent-encoded URL separators like '/'when decoding the host name part of a URL, making it a different URL usingthe wrong host name when it is later retrieved.For example, a URL like http://example.com%2F127.0.0.1/, would be allowed bythe parser and get...

fast-uri 路径遍历漏洞

fast-uri is an open-source, dependency-free RFC 3986 URI parser and toolkit developed by Fastify. Versions of fast-uri 3.1.0 and earlier contained a path traversal vulnerability. This vulnerability stemmed from the normalize and equal functions decoding percent-encoded path separators and dots,...

PT-2026-36919

Name of the Vulnerable Software and Affected Versions fast-uri versions prior to 3.1.1 Description The normalize and equal functions decode percent-encoded path separators and dot segments before performing dot-segment removal. This causes encoded path data to be treated as actual slashes and...

Improper Access Control

Caddy is vulnerable to Improper Access Control. The vulnerability is due to incorrect case-insensitive matching in the HTTP path request matcher when percent-encoded sequences are present, allowing attackers to alter request path casing and bypass path-based routing or attached access controls...

Traefik < 2.11.43 / 3.x < 3.6.14 Multiple Vulnerabilities

The version of Traefik installed on the remote macOS host is prior to 2.11.43 or 3.x prior to 3.6.14. It is, therefore, affected by multiple vulnerabilities: - An authentication bypass via StripPrefixRegex and ForwardAuth dot-segment normalization. When StripPrefixRegex processes URLs with...

Improper Input Encoding

Axios is vulnerable to Improper Input Encoding. The vulnerability is due to incorrect character mapping in the encode function, where safely percent-encoded null bytes %00 are converted back to raw null bytes, potentially leading to unsafe request data handling in affected usage scenarios...

CVE-2026-42040

Axios is a promise based HTTP client for the browser and Node.js. Prior to 1.15.1 and 0.31.1, the encode function in lib/helpers/AxiosURLSearchParams.js contains a character mapping charMap at line 21 that reverses the safe percent-encoding of null bytes. After encodeURIComponent'\x00' correctly...

SiYuan: Path Traversal via Double URL Encoding in `/export/` Endpoint (Incomplete Fix Bypass for CVE-2026-30869)

Summary The fix for CVE-2026-30869 in SiYuan v3.5.10 only added a denylist check IsSensitivePath but did not address the root cause — a redundant url.PathUnescape call in serveExport. An authenticated attacker can use double URL encoding %252e%252e to traverse directories and read arbitrary...

EUVD-2026-24559

OAuth2 Proxy is a reverse proxy that provides authentication using OAuth2 providers. Versions 7.5.0 through 7.15.1 have a configuration-dependent authentication bypass. Deployments are affected when all of the following are true: Use of skipauthroutes or the legacy skipauthregex; use of patterns...

@fastify/static vulnerable to route guard bypass via encoded path separators

Impact @fastify/static v9.1.0 and earlier decodes percent-encoded path separators %2F before filesystem resolution, but Fastify's router treats them as literal characters. This creates a routing mismatch: route guards on /admin/ do not match /admin%2Fsecret.html, but @fastify/static decodes it to...

GHSA-X428-GHPX-8J92 @fastify/static vulnerable to route guard bypass via encoded path separators

Impact @fastify/static v9.1.0 and earlier decodes percent-encoded path separators %2F before filesystem resolution, but Fastify's router treats them as literal characters. This creates a routing mismatch: route guards on /admin/ do not match /admin%2Fsecret.html, but @fastify/static decodes it to...
