CVE-2026-33440: CWE-918: Server-Side Request Forgery (SSRF) in WeblateOrg weblate
Weblate is a web based localization tool. In versions prior to 5.17, the ALLOWED_ASSET_DOMAINS setting applied only to the first issued requests and didn't restrict possible redirects. This issue has been fixed in version 5.17.
AI Analysis
Technical Summary
Weblate before version 5.17 contained an SSRF vulnerability where the ALLOWED_ASSET_DOMAINS configuration only restricted the first request but failed to limit subsequent redirects. This could allow an attacker with at least low privileges to induce the server to make requests to unintended domains. The vulnerability is addressed in version 5.17, which properly enforces domain restrictions on redirects.
Potential Impact
The vulnerability allows an attacker with low privileges to cause the Weblate server to make unauthorized requests to internal or external domains via redirects, potentially leading to information disclosure or interaction with internal services. The impact is limited to confidentiality loss without integrity or availability impact, as indicated by the CVSS vector (C:L/I:N/A:N).
Mitigation Recommendations
Upgrade Weblate to version 5.17 or later, where this SSRF vulnerability is fixed by properly enforcing ALLOWED_ASSET_DOMAINS restrictions on redirects. No other mitigation is indicated or required.
