Description
This security bulletin contains information about 3 vulnerabilities.
1) Server-Side Request Forgery (SSRF) (CVE-ID: N/A)
CWE-ID: CWE-918 - Server-Side Request Forgery (SSRF)
CVSSv4: 7.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:L/VA:N/SC:L/SI:N/SA:N]
The disclosed vulnerability allows a remote attacker to perform SSRF attacks.
The vulnerability exists due to insufficient validation of user-supplied input in the S3-backed content storage feature. A remote user can send a specially crafted HTTP request and trick the application to initiate requests to arbitrary systems.
Successful exploitation of this vulnerability may allow a remote attacker gain access to sensitive data, located in the local network or send malicious requests to other servers from the vulnerable system.
2) Missing Authorization (CVE-ID: N/A)
CWE-ID: CWE-862 - Missing Authorization
CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to bypass authorization checks.
The vulnerability exists due to missing authorization within the MCP tools when calling service layer methods directly. A remote user can write translations in arbitrary languages, read unauthorized translation strings, or permanently delete keys.
3) Missing Authorization (CVE-ID: N/A)
CWE-ID: CWE-862 - Missing Authorization
CVSSv4: 8.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a low-privileged authenticated attacker to read and overwrite project translations without the required editing or language-specific permissions.
The vulnerability exists due to missing authorization checks in Tolgee's MCP translation tools when they bypass permission checks enforced inside the corresponding REST handlers. A low-privileged authenticated attacker can invoke these tools using credentials with any project scope, including view-only access, to access translation text or overwrite translations in any language.
