CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:HSummary
CVE-2025-26356 is a high-severity Path Traversal: '.../...//' (CWE-35) vulnerability in Q-Free Maxtime. Its CVSS base score is 7.2 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Data from Local System (T1005); ranked in the top 46% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to SI-10 (Information Input Validation) and AC-3 (Access Enforcement) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-26356 is a path traversal vulnerability (CWE-35) located in the setActive endpoint of maxtime/api/database/database.lua within Q-Free MaxTime versions up to and including 2.11.0. The flaw permits an authenticated remote attacker to supply crafted HTTP requests that traverse directories and overwrite arbitrary sensitive files on the affected system. It carries a CVSS 3.1 base score of 7.2 reflecting network attack vector, low complexity, high-privileged access requirements, and high impact across confidentiality, integrity, and availability.
An authenticated remote attacker with administrative credentials can exploit the endpoint to replace critical files, potentially leading to configuration tampering, service disruption, or further system compromise. The attack requires no user interaction and can be executed over the network.
The sole reference points to a Nozomi Networks advisory that details the issue for Q-Free MaxTime.
EPSS for the CVE rose from a low baseline to a recorded peak of 0.0304 before settling at the current value of 0.0175, indicating emerging exploitation interest after disclosure.

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
Input validation directly neutralizes path sequences so the traversal cannot be introduced or exploited.
Enforces access authorizations on the resulting pathname, blocking traversal attempts from succeeding.
Enforces information flow rules that stop unauthorized directory escapes via crafted paths.
Least privilege reduces the impact of any successful traversal by limiting accessible resources.

Secure SDLC practices directly require input validation and path sanitization that neutralize traversal sequences.

Security testing in development can detect path-traversal flaws before release.
Secure SDLC mandates input validation and path-handling controls that directly mitigate path traversal.
Application security requirements include rules for safe file-path construction and canonicalization.
Secure architecture principles require proper directory restrictions and input sanitization to prevent traversal.
Secure coding standards explicitly forbid unsafe path concatenation and mandate canonicalization routines.
Information access restriction limits file reachability but does not address the input-validation flaw itself.
