{"id":"CVE-2026-33677","aliases":["GHSA-7c2g-p23p-4jg3","GO-2026-4846"],"url":"https://o3.security/vulnerability/CVE-2026-33677","summary":"Webhook BasicAuth Credentials Exposed to Read-Only Project Collaborators via API","details":"Vikunja is an open-source self-hosted task management platform. Prior to version 2.2.1, the `GET /api/v1/projects/:project/webhooks` endpoint returns webhook BasicAuth credentials (`basic_auth_user` and `basic_auth_password`) in plaintext to any user with read access to the project. While the existing code correctly masks the HMAC `secret` field, the BasicAuth fields added in a later migration were not given the same treatment. This allows read-only collaborators to steal credentials intended for authenticating against external webhook receivers. Version 2.2.1 patches the issue.","published":"2026-03-24T15:36:51.576Z","modified":"2026-08-12T03:51:17.337374096Z","cvss":{"score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"code.vikunja.io/api","fixedVersion":"2.2.1"}],"fix":null,"references":[{"type":"WEB","url":"https://vikunja.io/changelog/vikunja-v2.2.2-was-released"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33677.json"},{"type":"ADVISORY","url":"https://github.com/go-vikunja/vikunja/security/advisories/GHSA-7c2g-p23p-4jg3"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-33677"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:17.337374096Z"}}
