Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-111917 exists.\n\nAffected packages and fixed versions:\n- code.vikunja.io/api (Go): affected all versions; no fix listed\n- code.vikunja.io/api (Go): affected from 2.3.0; fixed in 2.7.0\n- code.vikunja.io/api (Go): affected from 2.3.0; fixed in 2.7.0\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-2026-111917/ (Markdown: https://insights.sbomify.com/CVE-2026-111917/index.md)","id":"CVE-2026-111917","markdown":"https://insights.sbomify.com/CVE-2026-111917/index.md","name":"CVE-2026-111917","record":{"aliases":["GHSA-355w-rx9g-pww7","GHSA-4hv6-xc92-j86g","GO-2026-6715"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Vikunja task manager","requires_auth":"low_privilege","summary":"Attackers with stolen tokens maintain WebSocket access after session revocation, continuing to receive private task and project notifications.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-613","name":"DEPRECATED: Insufficient Session Expiration"}],"description":"Vikunja 2.3.0 before 2.7.0 contains an improper session validation vulnerability that allows attackers to keep WebSocket access after revocation because handleAuth never checks the JWT sid claim against the sessions table.
