CVE-2025-34442
Published: 17 December 2025
Summary
CVE-2025-34442 is a medium-severity Exposure of Sensitive System Information to an Unauthorized Control Sphere (CWE-497) vulnerability in Wwbn Avideo. Its CVSS base score is 6.9 (Medium).
Operationally, ranked in the top 2.5% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
AVideo versions prior to 20.1 contain an information disclosure vulnerability tracked as CVE-2025-34442. Multiple public API endpoints return metadata containing absolute filesystem paths to media files, exposing the underlying server directory structure. The issue is classified under CWE-497 and carries a CVSS 4.0 score of 6.9 reflecting network attack vector, low complexity, and no required authentication or user interaction.
Unauthenticated remote attackers can query the affected endpoints to obtain full server paths. This information can be used to map the filesystem layout and support more targeted follow-on attacks against the AVideo installation or the host system.
Public references, including GitHub commits 4a53ab2056 and dbe3e91c54 along with the VulnCheck advisory, indicate that the path disclosure has been addressed in version 20.1. Security practitioners should apply the available updates to eliminate the exposed endpoints.
The EPSS score for this CVE rose from a low baseline to a peak of 0.4749 before settling at the current value of 0.4080, indicating emerging exploitation interest after disclosure.

Likely Mitigating Controls AI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Ongoing reviews detect and remove sensitive system information before it reaches publicly accessible systems.
Employs detection to prevent unauthorized mining of sensitive system information from being exfiltrated to external control spheres.
Documenting where system information is processed and stored prevents exposure to unauthorized control spheres.
The control stops sensitive system information from crossing into unauthorized control spheres through EM emanations.
Authorization and minimization requirements keep PII out of test/research control spheres that often lack production-grade protections.
Documented categorization of system information reduces the chance that sensitive internals are left exposed to unauthorized spheres.
System information is concealed or replaced with decoys, reducing leakage to unauthorized observers.
Ensures sensitive system information is not disclosed outside the intended control sphere through error output.
