{"cve":"CVE-2026-33679","nvd":{"published":"2026-03-24T16:16:35.420","modified":"2026-06-17T10:37:54.877","status":"Analyzed","description":"Vikunja is an open-source self-hosted task management platform. Prior to version 2.2.1, the `DownloadImage` function in `pkg/utils/avatar.go` uses a bare `http.Client{}` with no SSRF protection when downloading user avatar images from the OpenID Connect `picture` claim URL. An attacker who controls their OIDC profile picture URL can force the Vikunja server to make HTTP GET requests to arbitrary internal or cloud metadata endpoints. This bypasses the SSRF protections that are correctly applied to the webhook system. 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:C/C:L/I:L/A:L","score":7.4},"cwes":["CWE-918"],"references":["https://github.com/go-vikunja/vikunja/commit/363aa6642352b08fc8bc6aaff2f3a550393af1cf","https://github.com/go-vikunja/vikunja/security/advisories/GHSA-g9xj-752q-xh63","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-2026-33679","score":0.00402,"percentile":0.34475,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-g9xj-752q-xh63","url":"https://osv.dev/vulnerability/GHSA-g9xj-752q-xh63","summary":"Vikjuna Bypasses Webhook SSRF Protections During OpenID Connect Avatar Download ","modified":"2026-03-30T21:34:51.546877Z","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-2026-4852","url":"https://osv.dev/vulnerability/GO-2026-4852","summary":"Vikjuna Bypasses Webhook SSRF Protections During OpenID Connect Avatar Download in code.vikunja.io/api","modified":"2026-03-26T21:04:07.397031Z","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).
