  • •CVE-2026-29508 affects ReadyMedia versions 1.3.0 to 1.3.3.
  • •The vulnerability allows remote code execution via crafted DFF audio files.
  • •Public proof of concept code has been released, increasing urgency for patching.

A stack-based buffer overflow vulnerability (CVE-2026-29508) was identified in ReadyMedia (formerly MiniDLNA) versions 1.3.0 to 1.3.3, allowing remote attackers to execute code or crash the service by exploiting crafted DFF audio files. Attackers can place malicious files in monitored directories to trigger automatic parsing, potentially leading to remote code execution on unprotected builds or denial of service on hardened builds. The vulnerability has a CVSS score of 8.7, indicating high risk, and a public proof of concept has been released, raising urgency for mitigation. Affected systems include NAS devices, routers, and small-business servers that run ReadyMedia. The risk is particularly high for systems where untrusted users can write to monitored media folders. Currently, there is no confirmed in-the-wild exploitation reported, but the situation requires immediate attention from administrators.
