{"id":"CVE-2026-62294","summary":"Flameshot: OCTOU symlink attack via predictable /tmp path in Flameshot \"Open With\"","details":"Flameshot is powerful yet simple to use screenshot software. Prior to 14.0.0, the Open With feature wrote screenshots to a predictable temporary path and followed symlinks, creating a time-of-check to time-of-use race that allowed a local unprivileged attacker on the same machine to pre-plant a symlink and cause Flameshot to write PNG data through it, overwriting any file the victim user could write. This issue is fixed in version 14.0.0.","aliases":["GHSA-fqqf-4rj8-c392"],"modified":"2026-07-17T03:46:30.926617343Z","published":"2026-07-15T14:20:43.746Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-362","CWE-377"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/62xxx/CVE-2026-62294.json"},"references":[{"type":"WEB","url":"https://github.com/flameshot-org/flameshot/releases/tag/v14.0.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/62xxx/CVE-2026-62294.json"},{"type":"ADVISORY","url":"https://github.com/flameshot-org/flameshot/security/advisories/GHSA-fqqf-4rj8-c392"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-62294"},{"type":"FIX","url":"https://github.com/flameshot-org/flameshot/commit/936716b8d8b7052be461c3d5e2f88492b6eb3b96"},{"type":"FIX","url":"https://github.com/flameshot-org/flameshot/pull/4716"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/flameshot-org/flameshot","events":[{"introduced":"0"},{"fixed":"936716b8d8b7052be461c3d5e2f88492b6eb3b96"},{"fixed":"e408812d77ff1835957f85796c4cf737466bd69d"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"14.0.0"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["v14.0.rc3","v14.0.rc2","v14.0.rc1","v13.3.0","v13.2.0","v13.1.0","v13.0.1","v13.0.0","v13.0.rc2","v13.0.rc1","v12.1.0","v12.0.0","v12.0.rc1","v11.0.0","v11.0.rc1","v0.10.1","v0.10.0","v0.9.0.rc2","v0.9.0.rc1","v0.8.4","v0.8.3","v0.8.2","v0.8.1","v0.8.0","v0.8.0.rc1","v0.6.0","v0.5.1","v0.5.0","v0.4.2","v0.4.1","v0.4.0","v0.3.0","v0.2.1","v0.2.0","v0.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-62294.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N"}]}
