Summary

CVE-2026-41058 is a high-severity Path Traversal (CWE-22) vulnerability in Wwbn Avideo. Its CVSS base score is 8.1 (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; a public proof-of-concept is referenced.

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-2026-41058 is a path traversal vulnerability (CWE-22) in WWBN AVideo, an open source video platform, affecting versions 29.0 and below. The issue stems from an incomplete fix in the CloneSite `deleteDump` parameter, which lacks proper path traversal filtering. This allows attackers to supply `../../` sequences via a GET parameter to invoke `unlink()` on arbitrary files on the server. The vulnerability carries a CVSS v3.1 base score of 8.1 (AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H).

A low-privileged authenticated user (PR:L) can exploit this vulnerability remotely over the network (AV:N) with low attack complexity and no user interaction required. Successful exploitation enables deletion of arbitrary files, resulting in high integrity (I:H) and availability (A:H) impacts but no confidentiality loss (C:N).

GitHub security advisories, including GHSA-5879-4fmr-xwf2, GHSA-xmjm-86qv-g226, and GHSA-5879-4fmr-xwf2, document the flaw and reference prior related issues. Mitigation is available in commit 3c729717c26f160014a5c86b0b6accdbd613e7b2, which provides an updated fix; an earlier commit 941decd6d19e2e694acb75e86317d10fbb560284 contained only a partial remediation.

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.

PR.PS-02 partial match
prevents

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 none match
prevents

PR.AA-05 defines and reviews access policies but does not address code-level pathname neutralization, so neither direction prevents CWE-22.

finds

Security testing in development catches path traversal via static/dynamic analysis.

prevents

Secure SDLC mandates input validation and path sanitization that directly prevent path traversal.

prevents

Application security requirements include rules for safe file handling and canonicalization.

prevents

Secure architecture principles require least-privilege file access and directory isolation.

prevents

Secure coding standards explicitly forbid unsafe path construction and mandate safe APIs.

mitigates

Information access restriction limits which files an application may read or write.
