CVE-2026-54293

CVE-2026-54293 affects NLTK’s nltk.data.load() in Python. A TOCTOU-style flaw lets an attacker bypass the unsafe-path regex (UNSAFE_NO_PROTOCOL_RE) by using URL-encoded path separators (e.g., %2f, %2e%2e) and then decoding, enabling arbitrary local file reads prior to the fix. Affected until vers...

GHSA-H5X3-XFC9-M39H Symfony: UrlGenerator Dot-Segment Encoding Skips Every Other Chained `../` or `./` → Generated URL Collapses Off-Route Under RFC 3986 Normalization

Description Symfony\Component\Routing\Generator\UrlGenerator::doGenerate percent-encodes . and .. path segments so that the generated URL still resolves to the originating route after RFC 3986 §5.2.4 dot-segment removal which strict RFC-3986 consumers — routers, reverse proxies, HTTP clients —...

GHSA-XF64-8MW2-4GR2 Traefik has a StripPrefix Route-Level Auth Bypass via Path Normalization

Summary There is a high severity vulnerability in Traefik's StripPrefix middleware that allows an unauthenticated attacker to bypass route-level authentication and authorization. When a public router matches on a PathPrefix rule and applies the StripPrefix middleware, a request path containing...

CVE-2026-42272

Heimdall is a cloud native Identity Aware Proxy and Access Control Decision service. Prior to version 0.17.14, Heimdall handles URL-encoded slashes %2F in a case-sensitive manner, while percent-encoding is defined to be case-insensitive. As a result, the lowercase equivalent %2f is not recognized...

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-2026-8162

The CVE-2026-8162 entry affects multiparty (versions 4.2.3 and earlier) where a multipart/form-data request with a Content-Disposition filename* contains malformed percent-encoding. The parser calls decodeURI without a try/catch, causing a URIError to propagate as an uncaught exception and crash ...

CVE-2026-42882

oxyno-zeta/s3-proxy is an aws s3 proxy written in go. Prior to 5.0.0, s3-proxy contains an authentication bypass caused by inconsistent URL path interpretation between the authentication middleware and the bucket handler. The authentication middleware evaluates resource path patterns against the...

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

Impact fast-uri v3.1.0 and earlier decodes percent-encoded path separators %2F and dot segments %2E before applying dot-segment removal in normalize and equal. This makes encoded path data behave like real / and .., so distinct URIs collapse onto the same normalized path. For example,...

Nitro has a proxy scope bypass via percent-encoded path traversal in `routeRules`

A proxy route rule like: ts routeRules: "/api/orders/": proxy: to: "http://upstream/orders/" is intended to limit the proxy to URLs under /api/orders/. Before the patch, an attacker could bypass that scope by sending percent-encoded path traversal ..%2f in the URL, causing Nitro to forward a...

S3-Proxy has Security Issues in its Resource Path Matching Implementation

Background The original concern is functional: a resource pattern should treat a percent-encoded segment like some%2Fvalue as a single opaque token rather than splitting it into two path segments at the decoded /. Investigation into why %2F was being decoded and how routes matched against the...
