{"id":"UBUNTU-CVE-2026-62294","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.","modified":"2026-07-22T11:41:04.624729290Z","published":"2026-07-15T15:16:00Z","upstream":["CVE-2026-62294"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-62294"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-62294"},{"type":"REPORT","url":"https://github.com/flameshot-org/flameshot/security/advisories/GHSA-fqqf-4rj8-c392"},{"type":"REPORT","url":"https://github.com/flameshot-org/flameshot/pull/4716"}],"affected":[{"package":{"name":"flameshot","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/flameshot?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.5.0+git20180114-1","0.5.0+git20180222-1","0.5.1-1","0.5.1-2"],"ecosystem_specific":{"binaries":[{"binary_version":"0.5.1-2","binary_name":"flameshot"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-62294.json"}},{"package":{"name":"flameshot","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/flameshot?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.6.0+git20190714-1","0.6.0+git20191001-1","0.6.0+git20191001-2"],"ecosystem_specific":{"binaries":[{"binary_name":"flameshot","binary_version":"0.6.0+git20191001-2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-62294.json"}},{"package":{"name":"flameshot","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/flameshot?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.9.0+ds1-2","0.10.1+ds1-1","0.10.2+ds1-1","0.10.2+ds1-2","0.10.2+ds1-3","11.0~rc1+ds1-1","11.0~rc1+ds1-2","11.0.0-2"],"ecosystem_specific":{"binaries":[{"binary_name":"flameshot","binary_version":"11.0.0-2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-62294.json"}},{"package":{"name":"flameshot","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/flameshot?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["12.1.0-2","12.1.0-2build1","12.1.0-2build2"],"ecosystem_specific":{"binaries":[{"binary_name":"flameshot","binary_version":"12.1.0-2build2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-62294.json"}},{"package":{"name":"flameshot","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/flameshot?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["12.1.0+ds-2","12.1.0+ds-3","12.1.0+ds-4","13.3.0-1","13.3.0-2","13.3.0+git20251204-1"],"ecosystem_specific":{"binaries":[{"binary_name":"flameshot","binary_version":"13.3.0+git20251204-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-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"},{"type":"Ubuntu","score":"medium"}]}
