CVE-2026-54546: CWE-918: Server-Side Request Forgery (SSRF) in dfpc-coe CloudTAK
CloudTAK is a browser-based Common Operating Picture and situational awareness tool compatible with TAK. Prior to 13.22.1, the authenticated PUT /api/basemap endpoint passes an attacker-controlled URL through importBasemapURL() in api/routes/basemap.ts to fetch(url) without resolved-address classification or redirect revalidation. BasemapProtocol.isValidURL in api/lib/interface-basemap.ts checks only the HTTP or HTTPS scheme and is not applied on the vulnerable import path. Direct internal addresses, alternate IP encodings, and redirects to internal addresses can reach cloud metadata, loopback, private, and CGNAT HTTP services. The OptionalTileJSON response reflects fields including name, attribution, and tiles[0] to the caller, making the request forgery full-read rather than blind and enabling cloud credential theft and internal service disclosure. This issue is fixed in version 13.22.1.
AI Analysis
Technical Summary
CloudTAK, a browser-based situational awareness tool, contains an SSRF vulnerability in versions before 13.22.1. The PUT /api/basemap endpoint passes attacker-controlled URLs to a fetch function without proper resolved-address classification or redirect validation. The URL validation only checks for HTTP or HTTPS schemes but does not prevent access to internal IP addresses or alternate IP encodings. This flaw enables attackers to perform full-read SSRF attacks, exposing cloud metadata, loopback, private, and CGNAT HTTP services. The vulnerability allows theft of cloud credentials and disclosure of internal services. The vulnerability is addressed in CloudTAK version 13.22.1.
Potential Impact
An attacker with authentication can exploit this SSRF vulnerability to read internal network resources, including cloud metadata services and private HTTP endpoints. This can lead to theft of cloud credentials and disclosure of sensitive internal services. The vulnerability does not allow integrity or availability impact but can compromise confidentiality of internal data.
Mitigation Recommendations
A fix is available in CloudTAK version 13.22.1. Users should upgrade to this version or later to remediate the vulnerability. No additional mitigation steps are indicated by the vendor advisory.
