CVE-2026-78214

An authentication bypass vulnerability exists in the protection of Actuator endpoints. The application determines whether authentication is required by matching the incoming request path against protected Actuator paths. By sending a specially crafted request containing a percent-encoded path, a...

CVE-2026-62999

Copier is a library and CLI app for rendering project templates. From 9.5.0 through 9.16.0, percent-encoded parent-directory segments or encoded path separators in a template URL can match a configured trusted repository prefix before an HTTP server or Git transport decodes the path, allowing...

mailpit -- WebSocket origin check bypass via percent-encoded path

Mailpit author reports: The cross-site WebSocket hijacking fix was reimplemented as an origin check gated on a raw-URI prefix test, but Go's ServeMux routes on the percent-decoded path, so requesting /%61pi/events reaches the WebSocket handler while skipping the only origin control, and the...

GHSA-2GCR-MFCQ-WCC3 Hono: app.mount() strips mount prefix using undecoded path, causing incorrect routing for percent-encoded paths

Summary app.mount strips the mount prefix from the incoming request path using the raw URL pathname, while route matching is performed against the percent-decoded path. This inconsistency causes the prefix to be stripped at the wrong position when the path contains percent-encoded multi-byte...

CVE-2026-32847

DeepCode through commit c991dc2 contains a path traversal vulnerability in the SPA catch-all route in newui/backend/main.py that allows unauthenticated attackers to read arbitrary files by supplying percent-encoded path segments to the GET /fullpath:path endpoint. Attackers can bypass Starlette's...

CVE-2026-44373 Nitro: Proxy scope bypass via percent-encoded path traversal in `routeRules`

Nitro is a next generation server toolkit. Prior to 3.0.260429-beta, an attacker could bypass a proxy route rule by sending percent-encoded path traversal ..%2f in the URL, causing Nitro to forward a request that the upstream resolved outside the configured scope. This vulnerability is fixed in...

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...

Rack has Content-Length mismatch in Rack::Files error responses

Summary Rack::Filesfail sets the Content-Length response header using Stringsize instead of Stringbytesize. When the response body contains multibyte UTF-8 characters, the declared Content-Length is smaller than the number of bytes actually sent on the wire. Because Rack::Files reflects the...

Arbitrary File Read via Percent-Encoded Path Traversal in nltk.data.find() / nltk.data.load() - Incomplete Fix of Issue #3504

The security fix for path traversal PR 3522, pathsec module that was merged into NLTK 3.9.3 to address GitHub Issue 3504 is incomplete. The UNSAFENOPROTOCOLRE regex in data.py:57 checks for literal ../ but url2pathname on line 653 decodes percent-encoded sequences after the validation, not before...

CVE-2026-28807: Improper Limitation of a Pathname to a Restricted Directory

Improper Limitation of a Pathname to a Restricted Directory 'Path Traversal' vulnerability in gleam-wisp wisp allows arbitrary file read via percent-encoded path traversal. The wisp.servestatic function is vulnerable to path traversal because sanitization runs before percent-decoding. The encoded...
