Aug 13, 2026Form::Processor::Field::HtmlArea versions from 0.06 through 1.162360 for Perl allow attacker selected method dispatch and resource exhaustion via an HTML::Tidy CVE-2026-13051 · Other software · reported by 9b29abf9-4ab0-4765-b253-1875cd9b441eCritical 9.1
Form::Processor::Field::HtmlArea versions from 0.06 through 1.162360 for Perl allow attacker selected method dispatch and resource exhaustion via an HTML::Tidy diagnostic that validate passes to add_error as a Locale::Maketext template. validate runs HTML::Tidy over the submitted markup and passes each resulting message to add_error as its first argument, which add_error hands to the language handle as the Locale::Maketext message key. The default handle's lexicon sets `_AUTO`, so a message that is not a lexicon entry is compiled as a bracket notation template instead of being looked up. Tidy diagnostics quote the offending attribute name or value, so a bracket group in the submitted markup reaches the template position, where the first token of the group names a method called on the language handle and the remaining tokens are its arguments. A group such as `[0]` makes the compile croak, and neither the field nor the handle catches it, so the exception leaves validate. `[sprintf,%2000000000d,7]` reaches CORE::sprintf with an attacker chosen field width. One submission of crafted markup to an HtmlArea field throws an unhandled exception out of form validation or allocates an arbi

CodeChecker is an analyzer tooling, defect database and viewer extension for the Clang Static Analyzer and Clang Tidy. Cross-site request forgery allows an unauthenticated attacker to hijack the authentication of a logged in user, and use the web API with the same permissions, including but not limited to adding, removing or editing products. The attacker needs to know the ID of the available products to modify or delete them. The attacker cannot directly exfiltrate data (view) from CodeChecker, due to being limited to form-based CSRF.

CodeChecker is an analyzer tooling, defect database and viewer extension for the Clang Static Analyzer and Clang Tidy. Authentication method confusion allows logging in as the built-in root user from an external service. The built-in root user up until 6.24.1 is generated in a weak manner, cannot be disabled, and has universal access.This vulnerability allows an attacker who can create an account on an enabled external authentication service, to log in as the root user, and access and control everything that can be controlled via the web interface. The attacker needs to acquire the username of the root user to be successful. This issue affects CodeChecker: through 6.24.1.

CodeChecker is an analyzer tooling, defect database and viewer extension for the Clang Static Analyzer and Clang Tidy. Zip files uploaded to the server endpoint of `CodeChecker store` are not properly sanitized. An attacker, using a path traversal attack, can load and display files on the machine of `CodeChecker server`. The vulnerable endpoint is `/Default/v6.53/CodeCheckerService@massStoreRun`. The path traversal vulnerability allows reading data on the machine of the `CodeChecker server`, with the same permission level as the `CodeChecker server`. The attack requires a user account on the `CodeChecker server`, with permission to store to a server, and view the stored report. This vulnerability has been patched in version 6.23.
