From versions 1.3.0 to before 1.15.14, 1.16.0-rc.1 to before 1.16.14, and 1.17.0-rc.1 to before 1.17.5, a vulnerability has been found in Dapr that allows bypassing access control policies for service invocation using reserved URL characters and path traversal sequences in method paths. The ACL normalized the method path independently from the dispatch layer, so the ACL evaluated one path while the target application received a different one. This issue has been patched in versions 1.15.14, 1.16.14, and 1.17.5.","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:H/A:N","score":8.1},"cwes":["CWE-22","CWE-284"],"references":["https://github.com/dapr/dapr/pull/9589","https://github.com/dapr/dapr/security/advisories/GHSA-85gx-3qv6-4463"],"products":["linuxfoundation:dapr"],"source":"nvd","synced_at":"2026-10-19T22:33:55.586217763+00:00"},"epss":{"cve":"CVE-2026-41491","score":0.00325,"percentile":0.25608,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-85gx-3qv6-4463","url":"https://osv.dev/vulnerability/GHSA-85gx-3qv6-4463","summary":"Dapr: Service Invocation path traversal ACL bypass","modified":"2026-09-10T03:51:01.043082241Z","packages":[{"ecosystem":"Go","name":"github.com/dapr/dapr","purl":"pkg:golang/github.com/dapr/dapr","ranges":[">=1.17.0-rc.1 <1.17.5"],"fixed":["1.17.5"]},{"ecosystem":"Go","name":"github.com/dapr/dapr","purl":"pkg:golang/github.com/dapr/dapr","ranges":[">=1.16.0-rc.1 <1.16.14"],"fixed":["1.16.14"]},{"ecosystem":"Go","name":"github.com/dapr/dapr","purl":"pkg:golang/github.com/dapr/dapr","ranges":[">=1.3.0 <1.15.14"],"fixed":["1.15.14"]}]},{"id":"GO-2026-5242","url":"https://osv.dev/vulnerability/GO-2026-5242","summary":"Dapr: Service Invocation path traversal ACL bypass in github.com/dapr/dapr","modified":"2026-06-25T19:45:21.133629197Z","packages":[{"ecosystem":"Go","name":"github.com/dapr/dapr","purl":"pkg:golang/github.com/dapr/dapr","ranges":[">=1.3.0 <1.15.14",">=1.16.0-rc.1 <1.16.14",">=1.17.0-rc.1 <1.17.5"],"fixed":["1.15.14","1.16.14","1.17.5"]}]}],"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).
