CVE-2026-34831 Rack: Content-Length mismatch in Rack::Files error responses

Rack is a modular Ruby web server interface. Prior to versions 2.2.23, 3.1.21, and 3.2.6, 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...

CVE-2026-34973 phpMyFAQ has a LIKE Wildcard Injection in Search.php — Unescaped % and _ Metacharacters Enable Broad Content Disclosure

phpMyFAQ is an open source FAQ web application. Prior to version 4.1.1, the searchCustomPages method in phpmyfaq/src/phpMyFAQ/Search.php uses realescapestring via escape to sanitize the search term before embedding it in LIKE clauses. However, realescapestring does not escape SQL LIKE...

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...

BIT-MASTODON-2026-33868 Mastodon has a GET-Based Open Redirect via '/web/%2F<domain>'

Mastodon is a free, open-source social network server based on ActivityPub. Prior to versions 4.5.8, 4.4.15, and 4.3.21, an unauthenticated Open Redirect vulnerability CWE-601 exists in the /web/ route due to improper handling of URL-encoded path segments. An attacker can craft a specially encode...

CVE-2026-33868

Mastodon is affected by an unauthenticated Open Redirect (CWE-601) in the /web/* route prior to versions 4.5.8, 4.4.15, and 4.3.21. The root cause is improper handling of URL-encoded path segments, where encoded slashes (%2F) bypass Rails path normalization and are treated as host-relative redire...

CVE-2026-28807

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...

Rails Active Support has a possible XSS vulnerability in SafeBuffer#%

Impact SafeBuffer% does not propagate the @htmlunsafe flag to the newly created buffer. If a SafeBuffer is mutated in place e.g. via gsub! and then formatted with % using untrusted arguments, the result incorrectly reports htmlsafe? == true, bypassing ERB auto-escaping and possibly leading to XSS...

h3: Double Decoding in `serveStatic` Bypasses `resolveDotSegments` Path Traversal Protection via `%252e%252e`

Summary The serveStatic utility in h3 applies a redundant decodeURI call to the request pathname after H3Event has already performed percent-decoding with %25 preservation. This double decoding converts %252e%252e into %2e%2e, which bypasses resolveDotSegments since it checks for literal...
