CVE-2025-34452: Streama Subtitle Download Path Traversal and SSRF Leading to Arbitrary File Write

• Severity: high (CVSS 8.7 v4.0)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 5.4% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2025-12-18 · updated 2026-10-13
• Weakness: CWE-22

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.

Affected products

• Streama: from 1.10.0 through 1.10.5
