CVE-2026-80349 is a critical authentication bypass vulnerability in TarsCloud TarsWeb versions up to 3.0.14. The vulnerability arises because TarsWeb trusts the client-controlled X-Forwarded-For header without properly validating it, allowing an attacker to spoof the loopback address. This spoofing combined with a crafted uid query parameter enables unauthorized access as any user, including administrators, without credentials. Version 3.0.16 addresses this by separating the logic for trusted IPs and ignoring paths, assigning a default account instead of the user-supplied uid when the request comes from a trusted IP. The vulnerability has a CVSS 4.0 score of 9.3, indicating critical severity. No official patch or remediation level is currently confirmed.

CVE-2026-80348 is a high-severity vulnerability in TarsCloud TarsWeb versions up to and including 3.0.16. It involves missing authorization checks in four methods of the PatchController.js, allowing authenticated users with limited roles to perform unauthorized actions across applications. These actions include uploading and deploying packages to any server, downloading or deleting packages from any application, and changing the default deployed package. The vulnerability arises because some methods do not call the AuthService to enforce per-application role restrictions, enabling privilege escalation within the TarsWeb console.
