An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of GHSA-j5rm-v3vh-vx94 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- edumfa (PyPI): affected all versions; fixed in 2.9.1\n- edumfa (PyPI): affected all versions; fixed in 2.9.1\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-j5rm-v3vh-vx94/ (Markdown: https://insights.sbomify.com/GHSA-j5rm-v3vh-vx94/index.md)","id":"GHSA-j5rm-v3vh-vx94","markdown":"https://insights.sbomify.com/GHSA-j5rm-v3vh-vx94/index.md","name":"GHSA-j5rm-v3vh-vx94","record":{"aliases":[],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["account_takeover","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"eduMFA authentication system","requires_auth":"none","summary":"Attackers can replay expired WebAuthn challenges to bypass authentication and take over accounts in eduMFA.","user_interaction":"required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"### Impact\nIn eduMFA \u003c 2.9.1 userless Passkey/WebAuthn challenges might be replayed and do not expire\n\n### Patches\nFixed in eduMFA \u003e= 2.9.1 by adding validity information to the userless challenges.\n\n### Workarounds\nNo known workarounds besides disabling userless login altogether.","ecosystems":["PyPI"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":true,"headline":"eduMFA Passkeys: missing expiration flag may allow replay attacks and reuse of old challenges","id":"GHSA-j5rm-v3vh-vx94","indexable":true,"kev":null,"kind":"advisory","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"security_feature_bypass","year":"2026"},"n_packages":2,"n_references":null,"packages":[{"ecosystem":"PyPI","fixed":["2.9.1"],"introduced":["0"],"last_affected":[],"package":"edumfa","purl":null,"source":"GHSA-j5rm-v3vh-vx94"},{"ecosystem":"PyPI","fixed":["2.9.1"],"introduced":["0"],"last_affected":[],"package":"edumfa","purl":"pkg:pypi/edumfa","source":"GHSA-j5rm-v3vh-vx94"}],"products":null,"published":"2026-05-18","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":"Attackers can replay expired WebAuthn challenges to bypass authentication and take over accounts in eduMFA.","url":"https://insights.sbomify.com/GHSA-j5rm-v3vh-vx94/"}
