Threat & Defense Details
Likely Mitigating ControlsAI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
The access control policy and procedures directly mandate and enforce proper access control mechanisms across the organization.
Device lock enforces restricted access until re-authentication, directly reducing unauthorized use of active sessions.
Supervision and review of access control activities directly detects and remediates improper access configurations or usages.
Explicitly identifying and documenting actions permitted without identification or authentication enforces proper access control boundaries by defining justified exceptions.
By automatically labeling outputs with security attributes, the control supports attribute-based enforcement and reduces exploitability of improper access control weaknesses.
Associating and retaining security attributes with data directly supports enforcement of access control decisions across storage, processing, and transmission.
Requiring prior authorization for each remote access type prevents improper access control over remote connections.
Requiring authorization of wireless access before allowing connections enforces proper access control for this access method.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Improper access control directly enables unauthorized viewing (collection) and editing (stored data manipulation) of time entries in the application's information repository.

Deeper analysisAI
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.
