Deeper analysis
CVE-2026-21694 is an Improper Access Control vulnerability (CWE-284) in Titra, an open source project time tracking software. The flaw affects versions 0.99.49 and below, where users can view and edit other users' time entries in private projects to which they have not been granted access. It carries a CVSS v3.1 base score of 6.8 (AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:N), indicating medium severity with high confidentiality and integrity impacts but no availability effects.
Low-privileged authenticated users (PR:L) can exploit this over the network (AV:N), though it requires high attack complexity (AC:H) and no user interaction (UI:N). Attackers with such access can achieve high confidentiality by viewing unauthorized time entries in private projects and high integrity by editing them, potentially leading to data tampering or exposure of sensitive project details.
The vulnerability is fixed in Titra version 0.99.50. GitHub security advisories (GHSA-mr2r-wjf8-cj3c) and the fixing commit (29e6b88eca005107729e45a6f1731cf0fa5f8938) on the Titra repository detail the patch, recommending an upgrade to the remedied version for mitigation.

Directly enforces approved authorizations for logical access to time-entry objects, blocking the unauthorized view/edit of private-project entries described in the CVE.
Limits each user to the minimum set of privileges needed for their own time entries, preventing the over-privileged access that the flaw permits.
Requires prompt installation of the vendor patch (0.99.50) that corrects the improper access-control logic in Titra.
