What is CVE-2025-34452?
CVE-2025-34452 is a high-severity path traversal vulnerability in Streama, published on 18 Dec 2025. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
Streama versions 1.10.0 through 1.10.5 and prior to commit b7c8767 contain a combination of path traversal and server-side request forgery (SSRF) vulnerabilities in that allow an authenticated attacker to write arbitrary files to the server filesystem. The issue exists in the subtitle download functionality, where user-controlled parameters are used to fetch remote content and construct file paths without proper validation. By supplying a crafted subtitle download URL and a path traversal sequence in the file name, an attacker can write files to arbitrary locations on the server, potentially leading to remote code execution.
