CVE-2026-88011 Traefik: ForwardAuth identity spoofing via dot-form header alias

Traefik is an open source HTTP reverse proxy and load balancer. Prior to 2.11.56, and from 3.0.0 until 3.7.12, a client-supplied dot-form header such as X.Authenticated.User survives ForwardAuth replacement and underscoreHeadersStrategy because Go treats it as distinct from X-Authenticated-User...

CVE-2026-88011

Traefik 's ForwardAuth middleware is vulnerable to identity spoofing via dot-form header aliases (e.g. X.Authenticated.User). Go treats these as distinct from the canonical dash-form header, but backends such as PHP, CGI, WSGI, and NGINX collapse both into the same variable, allowing a permitted ...

CVE-2026-88879

Traefik (HTTP reverse proxy and load balancer) is vulnerable to identity spoofing via dot-form header aliasing in versions v1.x, v2.x–v2.11.55, and v3.0.0–v3.7.11. Because Go canonicalizes header names on dashes only, a client can send a dot-form alias (e.g., X.Authenticated.User) alongside the c...

CVE-2026-88879 Traefik before v2.11.56 Identity Spoofing via Header Alias

Traefik is an HTTP reverse proxy and load balancer. In Traefik v1.x, v2.x through v2.11.55, and v3.0.0 through v3.7.11, header names are canonicalized only on dashes, so X-Auth-User, XAuthUser and X.Auth.User are treated as three distinct headers by Traefik, while backends that derive variable...

NLTK: Uncontrolled search path when invoking the Graphviz 'dot' binary

Two NLTK sites executed the Graphviz dot program by bare name, so process creation resolved it via the search path — and on Windows via the current working directory — rather than a validated absolute location. An attacker who can place a file named dot where resolution looks the CWD on Windows, ...

PT-2026-89390

Summary There is a medium severity vulnerability in Traefik's handling of request headers whose name aliases another header name. Go canonicalizes header names on dashes only, so X-Auth-User, X Auth User and X.Auth.User are three distinct headers to Traefik, while backends that derive variable...

SUSE CVE-2026-55874

SeaweedFS is a distributed storage system. Prior to 4.34, the S3 API gateway does not reject dot-dot path segments in the X-Amz-Copy-Source header used by CopyObject and UploadPartCopy, allowing an authenticated identity scoped to one bucket to read objects from other buckets through server-side...

GHSA-65FR-J4P9-VC33 mongodb: Reject "." and NUL bytes in database and collection names

Impact Passing untrusted input as part of a database or collection name may result in targeting a different database or collection than specified. Patches Fixed in PHP library 1.21.4 and 2.4.1. Workarounds Validate database and collection names prior to passing into APIs...

GHSA-G6GW-C38X-MQFC Hono: Unbounded dot-notation nesting in `parseBody()` can cause memory exhaustion

Summary When parseBody expands dot-separated form field names into nested objects, it does not limit the nesting depth or the total number of objects created. A request body well within a normal size limit can therefore allocate an object graph far larger than the request itself, and concurrent...

CVE-2026-86253 h3 before 1.15.6 Path Traversal via Percent-Encoded Dot Segments

h3 npm package versions = 2.0.1-rc.14 contain a path traversal vulnerability in serveStatic. On Node.js deployments, event.url.pathname is not normalized, so percent-encoded dot segments %2e%2e are passed to decodeURI and decoded to ../ sequences without sanitization. An unauthenticated remote...

PT-2026-86520

h3 versions before 1.15.9 contain a path traversal vulnerability in the serveStatic utility. A double-decoding flaw allows a request path containing double-encoded dot sequences e.g. %252e%252e to be decoded to %2e%2e, which survives resolveDotSegments because that function only checks for litera...

CVE-2026-86195
