CVE-2026-56651: CWE-59 Improper Link Resolution Before File Access ('Link Following') in scottchiefbaker dool
Description
Dool versions up to 1.3.8 have a vulnerability related to improper symlink handling when the "--devel" flag is used. The application opens a log file without the O_NOFOLLOW flag, allowing a local attacker to create a symbolic link at the log file path that points to a sensitive file. This can cause dool to overwrite the target file with log data, which is particularly dangerous if dool runs with elevated privileges. The issue was fixed in a pull request #116.

Technical Analysis
CVE-2026-56651 is a CWE-59 (Improper Link Resolution Before File Access) vulnerability in the dool application by scottchiefbaker. When the "--devel" flag is used, dool opens a log file without the O_NOFOLLOW flag, enabling a local attacker to exploit symlink following. By creating a symbolic link at the expected log file location pointing to a sensitive file, the attacker can cause dool to truncate and overwrite that file with log data. This vulnerability affects versions up to 1.3.8 and was addressed by pull request #116.
Potential Impact
A local attacker can overwrite arbitrary files accessible by the dool process by exploiting symlink following, potentially leading to data loss or corruption. The impact is higher if dool is executed with elevated privileges, as critical system or sensitive files could be overwritten. The CVSS score is low (2.0), reflecting the requirement for local access and user interaction.
Mitigation Recommendations
A fix has been implemented in pull request #116, which addresses the issue by preventing symlink following when opening the log file. Users should upgrade to a version that includes this fix. Since no official patch version is explicitly stated, check the vendor repository or releases for the merged fix. Until then, avoid using the "--devel" flag or running dool with elevated privileges to reduce risk.
