Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2026-29058 is a critical command injection vulnerability (CWE-78) affecting AVideo, an open-source video-sharing platform software. Prior to version 7.0, the vulnerability enables unauthenticated attackers to execute arbitrary operating system commands on the server by injecting shell command substitution into the base64Url GET parameter. The issue carries a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), indicating high confidentiality, integrity, and availability impacts with network accessibility and no privileges required.
Any unauthenticated remote attacker can exploit this vulnerability over the network with low complexity, without user interaction. Successful exploitation allows arbitrary OS command execution, potentially resulting in full server compromise, data exfiltration such as configuration secrets, internal keys, and credentials, as well as service disruption through denial-of-service actions.
The GitHub security advisory (GHSA-9j26-99jh-v26q) confirms the vulnerability has been addressed in AVideo version 7.0, recommending immediate upgrades to mitigate the risk. No workarounds are specified in available details.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation can discover missing or incorrect command sanitization during development.
Input validation directly neutralizes or rejects special characters that would otherwise alter OS command structure.
Least privilege reduces the permissions available to any process that could be subverted by injected commands.
Least functionality restricts available OS commands and interpreters, limiting the blast radius of injection.
Secure engineering principles require proper neutralization of untrusted input before command construction.

PR.PS-06's SDLC practices directly require secure coding and input handling that blocks command-injection defects, yet the single broad outcome leaves many specific neutralization vectors and verification gaps unaddressed.
Routine patching/maintenance can remediate known command-injection CVEs in dependencies (partial forward) but does nothing to stop developers from introducing improper neutralization in custom code (none reverse).
