CVE-2026-34244: CWE-200: Exposure of Sensitive Information to an Unauthorized Actor in WeblateOrg weblate
Weblate is a web based localization tool. In versions prior to 5.17, a user with the project.edit permission (granted by the per-project "Administration" role) can configure machine translation service URLs pointing to arbitrary internal network addresses. During configuration validation, Weblate makes an HTTP request to the attacker-controlled URL and reflects up to 200 characters of the response body back to the user in an error message. This constitutes a Server-Side Request Forgery (SSRF) with partial response read. This issue has been fixed in version 5.17. If developers are unable to immediately upgrade, they can limit available machinery services via WEBLATE_MACHINERY setting.
AI Analysis
Technical Summary
CVE-2026-34244 is a medium severity vulnerability in Weblate before version 5.17. A user granted the project.edit permission can configure machine translation service URLs to point to attacker-controlled internal network addresses. During validation, Weblate performs an HTTP request to the specified URL and reflects up to 200 characters of the response body in an error message. This behavior constitutes an SSRF vulnerability with partial response exposure (CWE-918 and CWE-200). The vulnerability allows unauthorized exposure of sensitive information from internal network resources. The issue is resolved in Weblate 5.17.
Potential Impact
An attacker with project.edit permission can exploit this vulnerability to make Weblate perform HTTP requests to internal network addresses and receive partial response data. This may lead to unauthorized exposure of sensitive internal information. The CVSS score is 5.0 (medium severity), indicating limited confidentiality impact without integrity or availability effects. There are no known exploits in the wild.
Mitigation Recommendations
Upgrade Weblate to version 5.17 or later, where this vulnerability is fixed. If immediate upgrade is not feasible, restrict the machine translation services available by configuring the WEBLATE_MACHINERY setting to limit URLs that can be used, thereby reducing the SSRF attack surface.
