Bytebase before 3.16.0 contains an authorization bypass vulnerability in the UpdateIssueComment handler that allows low-privileged project users to modify comments in other projects by supplying a foreign comment UID. Attackers with any project role, including Project Viewer, can set their own project's issue as parent and reference another project's comment UID to overwrite comments they cannot access.
