CVE-2026-1616 is a high-severity Path Traversal (CWE-22) vulnerability in Redhat Open Security Issue Management. Its CVSS base score is 7.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 38th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2026-1616 is a path traversal vulnerability (CWE-22) affecting Open Security Issue Management (OSIM) versions prior to v2025.9.0. The flaw arises from improper concatenation of the $uri and $args variables in the nginx configuration file, enabling attackers to manipulate query parameters to traverse directories and access unintended files.
With a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), the vulnerability is exploitable remotely over the network with low complexity, requiring no privileges or user interaction. Unauthenticated attackers can send crafted HTTP requests containing malicious query parameters to achieve directory traversal, resulting in high-impact unauthorized disclosure of confidential data without affecting integrity or availability.
The GitHub pull request at https://github.com/RedHatProductSecurity/osim/pull/615 provides the patch addressing this issue, and upgrading to OSIM v2025.9.0 or later mitigates the vulnerability.

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.

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.
