{"cve":"CVE-2026-33677","nvd":{"published":"2026-03-24T16:16:35.113","modified":"2026-06-17T10:37:54.663","status":"Analyzed","description":"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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","score":6.5},"cwes":["CWE-200"],"references":["https://github.com/go-vikunja/vikunja/security/advisories/GHSA-7c2g-p23p-4jg3","https://vikunja.io/changelog/vikunja-v2.2.2-was-released"],"products":["vikunja:vikunja"],"source":"nvd","synced_at":"2026-10-19T22:26:19.218427112+00:00"},"epss":{"cve":"CVE-2026-33677","score":0.00302,"percentile":0.23036,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-7c2g-p23p-4jg3","url":"https://osv.dev/vulnerability/GHSA-7c2g-p23p-4jg3","summary":"Vikjuna: Webhook BasicAuth Credentials Exposed to Read-Only Project Collaborators via API","modified":"2026-03-26T21:11:07.555748Z","packages":[{"ecosystem":"Go","name":"code.vikunja.io/api","purl":"pkg:golang/code.vikunja.io/api","ranges":["<2.2.1"],"fixed":["2.2.1"]}]},{"id":"GO-2026-4846","url":"https://osv.dev/vulnerability/GO-2026-4846","summary":"Vikjuna: Webhook BasicAuth Credentials Exposed to Read-Only Project Collaborators via API in code.vikunja.io/api","modified":"2026-03-26T21:04:13.855478Z","packages":[{"ecosystem":"Go","name":"code.vikunja.io/api","purl":"pkg:golang/code.vikunja.io/api","ranges":["all versions"],"fixed":[]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
