CVE-2026-56651

LOWCVSS 2/10EPSS 0.15%

Last modified

CVE-2026-56651 is a low-severity vulnerability rated 2/10 on the CVSS scale. Dool in versions up to 1.3.8 is vulnerable to symlink following when the "--devel" flag is used, as the application opens a log file without the "O_NOFOLLOW" flag. A local attacker can exploit this by creating a symlink at the expected log file path pointing to a sensitive file, causing dool to truncate and overwrite the target file with log data, which is especially impactful if dool is run with elevated privileges. The issue was addressed by pull request #116. EPSS estimates a 0.15% chance of exploitation in the next 30 days.
