Summary

CVE-2025-58760 is a high-severity Relative Path Traversal (CWE-23) vulnerability in Tautulli Tautulli. Its CVSS base score is 8.6 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 47th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SI-10 (Information Input Validation) and AC-3 (Access Enforcement) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2025-58760 is a path traversal vulnerability (CWE-23) in the `/image` API endpoint of Tautulli, a Python-based monitoring and tracking tool for Plex Media Server. Affecting versions 2.15.3 and earlier, the endpoint, which serves static images from the application's data directory without authentication, allows attackers to traverse outside the intended directory and access arbitrary files on the application server's filesystem. The issue carries a CVSS v3.1 base score of 8.6 (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N), reflecting high confidentiality impact with changed scope.

Unauthenticated remote attackers can exploit this vulnerability by sending crafted requests to the `/image` endpoint, enabling them to read sensitive files such as the `tautulli.db` SQLite database containing active JWT tokens and the `config.ini` file with the hashed admin password, JWT token secret, Plex Media Server token, and connection details. Successful exfiltration of these files could allow privilege escalation to administrative control if the hashed password is cracked or a valid JWT token is reused.

The Tautulli GitHub security advisory (GHSA-8g4r-8f3f-hghp) and the fixing commit (47566128e2e5dde98980d59b7a51b98173bc0b40) confirm that version 2.16.0 resolves the vulnerability by addressing the path traversal in the endpoint. Security practitioners should upgrade to 2.16.0 or later and review access logs for suspicious `/image` requests.

Vulnerability Data

Tautulli is a Python based monitoring and tracking tool for Plex Media Server. The `/image` API endpoint in Tautulli v2.15.3 and earlier is vulnerable to path traversal, allowing unauthenticated attackers to read arbitrary files from the application server's filesystem. In…

more

Tautulli, the `/image` API endpoint is used to serve static images from the application's data directory to users. This endpoint can be accessed without authentication, and its intended purpose is for server background images and icons within the user interface. Attackers can exfiltrate files from the application file system, including the `tautulli.db` SQLite database containing active JWT tokens, as well as the `config.ini` file which contains the hashed admin password, the JWT token secret, and the Plex Media Server token and connection details. If the password is cracked, or if a valid JWT token is present in the database, an unauthenticated attacker can escalate their privileges to obtain administrative control over the application. Version 2.16.0 contains a fix for the issue.

Mitigating Controls (NIST 800-53 r5) AI

Explicit validation of path inputs stops .. sequences from ever being interpreted by the file system.

Access enforcement directly blocks unauthorized file reads/writes that result from unresolved .. sequences.

Information-flow rules can be configured to reject traversals that would move data outside an approved directory boundary.

Least privilege reduces the set of reachable files even when a traversal succeeds.

Secure-engineering principles require safe pathname construction and input neutralization before any file operation.

finds

Security testing in development catches path traversal via static/dynamic analysis, but does not itself implement the fix.

prevents

Secure development lifecycle mandates input validation and path-handling controls that directly prevent relative path traversal.

prevents

Application security requirements explicitly call for controls against path traversal and other injection flaws.

prevents

Secure architecture principles include directory isolation and canonicalization, reducing but not eliminating traversal risk.

prevents

Secure coding standards require neutralizing path traversal sequences, directly addressing CWE-23.

mitigates

Information access restriction limits which files can be reached, mitigating impact but not preventing the traversal flaw.
