An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of GHSA-3wqc-mwfx-672p in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/traefik/traefik/v2 (Go): affected all versions; fixed in 2.11.24\n- github.com/traefik/traefik/v2 (Go): affected all versions; fixed in 2.11.24\n- github.com/traefik/traefik/v3 (Go): affected all versions; fixed in 3.3.6\n- github.com/traefik/traefik/v3 (Go): affected all versions; fixed in 3.3.6\n- github.com/traefik/traefik/v3 (Go): affected from 3.4.0-rc1; fixed in 3.4.0-rc2\n- github.com/traefik/traefik/v3 (Go): affected from 3.4.0-rc1; fixed in 3.4.0-rc2\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/GHSA-3wqc-mwfx-672p/ (Markdown: https://insights.sbomify.com/GHSA-3wqc-mwfx-672p/index.md)","id":"GHSA-3wqc-mwfx-672p","markdown":"https://insights.sbomify.com/GHSA-3wqc-mwfx-672p/index.md","name":"GHSA-3wqc-mwfx-672p","record":{"aliases":[],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Traefik reverse proxy","requires_auth":"none","summary":"Traefik is vulnerable to improper input validation in its OAuth2/JWS library, potentially allowing security bypasses; users should upgrade to patched versions.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"### Summary\nWe have encountered a security vulnerability being reported by our scanners for Traefik 2.11.22.\n- https://security.snyk.io/vuln/SNYK-CHAINGUARDLATEST-TRAEFIK33-9403297\n\n### Details\nIt seems to target oauth2/jws library.\n\n### PoC\nNo steps to replicate this vulnerability\n\n### Impact\nWe have a strict control on security and we always try to stay up-to-date with the fixes received for third-party solutions.\n\n## Patches\n\n- https://github.com/traefik/traefik/releases/tag/v2.11.24\n- https://github.com/traefik/traefik/releases/tag/v3.3.6\n- https://github.com/traefik/traefik/releases/tag/v3.4.0-rc2","ecosystems":["Go"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":true,"headline":"Traefik affected by Go oauth2/jws Improper Validation of Syntactic Correctness of Input vulnerability","id":"GHSA-3wqc-mwfx-672p","indexable":true,"kev":null,"kind":"advisory","links":{"ecosystem":"Go","product":null,"products":[],"type":"other","year":"2025"},"n_packages":6,"n_references":null,"packages":[{"ecosystem":"Go","fixed":["2.11.24"],"introduced":["0"],"last_affected":[],"package":"github.com/traefik/traefik/v2","purl":null,"source":"GHSA-3wqc-mwfx-672p"},{"ecosystem":"Go","fixed":["2.11.24"],"introduced":["0"],"last_affected":[],"package":"github.com/traefik/traefik/v2","purl":"pkg:golang/github.com/traefik/traefik/v2","source":"GHSA-3wqc-mwfx-672p"},{"ecosystem":"Go","fixed":["3.3.6"],"introduced":["0"],"last_affected":[],"package":"github.com/traefik/traefik/v3","purl":null,"source":"GHSA-3wqc-mwfx-672p"},{"ecosystem":"Go","fixed":["3.3.6"],"introduced":["0"],"last_affected":[],"package":"github.com/traefik/traefik/v3","purl":"pkg:golang/github.com/traefik/traefik/v3","source":"GHSA-3wqc-mwfx-672p"},{"ecosystem":"Go","fixed":["3.4.0-rc2"],"introduced":["3.4.0-rc1"],"last_affected":[],"package":"github.com/traefik/traefik/v3","purl":null,"source":"GHSA-3wqc-mwfx-672p"},{"ecosystem":"Go","fixed":["3.4.0-rc2"],"introduced":["3.4.0-rc1"],"last_affected":[],"package":"github.com/traefik/traefik/v3","purl":"pkg:golang/github.com/traefik/traefik/v3","source":"GHSA-3wqc-mwfx-672p"}],"products":null,"published":"2025-04-18","related":[],"sources":[{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":"Traefik is vulnerable to improper input validation in its OAuth2/JWS library, potentially allowing security bypasses; users should upgrade to patched versions.","url":"https://insights.sbomify.com/GHSA-3wqc-mwfx-672p/"}
