Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2026-2749 is a path traversal vulnerability (CWE-22) in the Centreon Open Tickets module on Centreon Central Server running on Linux, specifically affecting the Centreon Open Ticket modules. This issue impacts all versions prior to 25.10.3, 24.10.8, and 24.04.7. Published on 2026-02-27, it carries a CVSS v3.1 base score of 9.9 (AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H), indicating critical severity due to its potential for severe impact across the confidentiality, integrity, and availability triads.
The vulnerability can be exploited by an authenticated attacker with low privileges over the network, requiring low attack complexity and no user interaction. Exploitation enables high-impact outcomes, including unauthorized access to sensitive data, modification of system files, and disruption of services, amplified by a scope change that affects the broader system.
The official Centreon security bulletin at https://thewatch.centreon.com/latest-security-bulletins-64/cve-2026-2749-centreon-open-tickets-critical-severity-5493 details the issue and recommends mitigation by upgrading to Centreon Open Tickets versions 25.10.3, 24.10.8, 24.04.7, or later.

Mitigating Controls (NIST 800-53 r5) AI
Enforces the intended directory access authorizations that path traversal would otherwise bypass.
Input validation directly neutralizes special path elements before pathname construction occurs.
Least privilege reduces the impact of any unauthorized file access obtained via traversal.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Patching/maintenance can remediate known path-traversal flaws in deployed software (partial prevention of exploitability) but does nothing to stop the coding defect from being introduced in the first place.
PR.AA-05 defines and reviews access policies but does not address code-level pathname neutralization, so neither direction prevents CWE-22.

Security testing in development catches path traversal via static/dynamic analysis.
Secure SDLC mandates input validation and path sanitization that directly prevent path traversal.
Application security requirements include rules for safe file handling and canonicalization.
Secure architecture principles require least-privilege file access and directory isolation.
Secure coding standards explicitly forbid unsafe path construction and mandate safe APIs.
Information access restriction limits which files an application may read or write.
