An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-41669 exists.\n\nAffected packages and fixed versions:\n- admidio/admidio (Packagist): affected all versions; fixed in 5.0.9\n- admidio/admidio (Packagist): affected all versions; fixed in 5.0.9\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/CVE-2026-41669/ (Markdown: https://insights.sbomify.com/CVE-2026-41669/index.md)","id":"CVE-2026-41669","markdown":"https://insights.sbomify.com/CVE-2026-41669/index.md","name":"CVE-2026-41669","record":{"aliases":["GHSA-25cw-98hg-g3cg"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["security_bypass","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Admidio user management","requires_auth":"none","summary":"Admidio ignores SAML signature validation results, allowing attackers to forge authentication and logout requests to bypass security controls.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":8.2,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-347","name":"Improper Verification of Cryptographic Signature"}],"description":"Admidio is an open-source user management solution. Prior to version 5.0.9, the Admidio SAML Identity Provider implementation discards the return value of its validateSignature() method at both call sites (handleSSORequest() line 418 and handleSLORequest() line 613). The method returns error strings on failure rather than throwing exceptions, but the developer believed it would throw (per comments on lines 416 and 611). This means the smc_require_auth_signed configuration option is completely ineffective — unsigned or invalidly-signed SAML AuthnRequests and LogoutRequests are processed identically to properly signed ones.
