{"cve":"CVE-2026-44884","nvd":{"published":"2026-05-28T22:16:59.677","modified":"2026-07-21T10:10:00.103","status":"Analyzed","description":"Portainer Community Edition is a lightweight service delivery platform for containerized applications that can be used to manage Docker, Swarm, Kubernetes and ACI environments. From 2.33.0 to before 2.33.8 and 2.39.1, a missing authorization vulnerability in the Custom Template file endpoint (GET /api/custom_templates/{id}/file) allows any authenticated user to read the file content of any custom template by enumerating sequential integer IDs, bypassing Resource Control access restrictions. Template files may contain environment-specific values such as connection strings, API tokens, or registry credentials that administrators would not expect standard users to read. This vulnerability is fixed in 2.33.8 and 2.39.1.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","score":6.0},"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-862"],"references":["https://github.com/portainer/portainer/security/advisories/GHSA-cqpq-2fgr-8mvc"],"products":["portainer:portainer"],"source":"nvd","synced_at":"2026-10-19T22:36:28.938604137+00:00"},"epss":{"cve":"CVE-2026-44884","score":0.00257,"percentile":0.17432,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-cqpq-2fgr-8mvc","url":"https://osv.dev/vulnerability/GHSA-cqpq-2fgr-8mvc","summary":"Portainer missing authorization on custom template file endpoint, which exposes template content","modified":"2026-06-25T19:56:37.031894001Z","packages":[{"ecosystem":"Go","name":"github.com/portainer/portainer","purl":"pkg:golang/github.com/portainer/portainer","ranges":[">=2.33.0 <2.33.8"],"fixed":["2.33.8"]},{"ecosystem":"Go","name":"github.com/portainer/portainer","purl":"pkg:golang/github.com/portainer/portainer","ranges":[">=2.39.0 <2.39.1"],"fixed":["2.39.1"]}]},{"id":"GO-2026-5333","url":"https://osv.dev/vulnerability/GO-2026-5333","summary":"Portainer missing authorization on custom template file endpoint, which exposes template content in github.com/portainer/portainer","modified":"2026-06-25T19:45:31.922613718Z","packages":[{"ecosystem":"Go","name":"github.com/portainer/portainer","purl":"pkg:golang/github.com/portainer/portainer","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).
