It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-111922 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 2.2.0 up to 2.6.0; no fix listed\n- code.vikunja.io/api (Go): affected from 2.2.0 up to 2.6.0; no fix listed\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-2026-111922/ (Markdown: https://insights.sbomify.com/CVE-2026-111922/index.md)","id":"CVE-2026-111922","markdown":"https://insights.sbomify.com/CVE-2026-111922/index.md","name":"CVE-2026-111922","record":{"aliases":["GHSA-m687-p538-r5hp","GHSA-r87c-f263-6pfc","GO-2026-6739"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["account_takeover"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Vikunja task manager","requires_auth":"none","summary":"Attackers on localhost can steal JWT tokens via permissive CORS to take over user accounts in Vikunja.","user_interaction":"required","vuln_class":"misconfiguration"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":7.2,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:P/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-942","name":"Permissive Cross-domain Security Policy with Untrusted Domains"}],"description":"Vikunja from 2.2.0 before 2.7.0 contains a permissive CORS configuration that trusts every localhost and 127.0.0.1 port with credentials, even when service.publicurl is set.
