{"id":"CVE-2026-32805","aliases":["GHSA-p799-g7vv-f279","GO-2026-4719"],"url":"https://o3.security/vulnerability/CVE-2026-32805","summary":"Romeo is vulnerable to Archive Slip due to missing checks in sanitization","details":"Romeo gives the capability to reach high code coverage of Go ≥1.20 apps by helping to measure code coverage for functional and integration tests within GitHub Actions. Prior to version 0.2.2, the `sanitizeArchivePath` function in `webserver/api/v1/decoder.go` (lines 80-88) is vulnerable to a path traversal bypass due to a missing trailing path separator in the `strings.HasPrefix` check. A crafted tar archive can write files outside the intended destination directory. Version 0.2.2 fixes the issue.","published":"2026-03-18T22:24:29.102Z","modified":"2026-08-07T11:48:54.111547639Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/ctfer-io/romeo/webserver","fixedVersion":"0.2.2"}],"fix":{"url":"https://github.com/ctfer-io/romeo/commit/c2ebcfb9f305fd5f6ef68858de82507dbac10263","label":"ctfer-io/romeo@c2ebcfb"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/32xxx/CVE-2026-32805.json"},{"type":"ADVISORY","url":"https://github.com/ctfer-io/romeo/security/advisories/GHSA-p799-g7vv-f279"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-32805"},{"type":"FIX","url":"https://github.com/ctfer-io/romeo/commit/c2ebcfb9f305fd5f6ef68858de82507dbac10263"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T11:48:54.111547639Z"}}
