Detailsinfo

A vulnerability, which was classified as problematic, has been found in PoxenStudio Talebook up to 3.41.x. Affected by this issue is the function AdminSettings.post of the file webserver/handlers/admin.py of the component Admin Settings. The manipulation of the argument social_auth with an unknown input leads to a code injection vulnerability. Using CWE to declare the problem leads to CWE-94. The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. Impacted is confidentiality, integrity, and availability. CVE summarizes:

MyBooks is an enhanced and easy-to-use personal ebook management web server also known as Talebook. In 3.41.2 and earlier, the AdminSettings.post handler in webserver/handlers/admin.py accepts SOCIAL_AUTH key names without validating quotes or newline characters, and SettingsLoader.dumpfile in webserver/loader.py concatenates those names into the generated Python source file auto.py without escaping them. An administrator can submit a crafted SOCIAL_AUTH key name that closes the settings dictionary and injects arbitrary Python statements. The application later executes those statements because SettingsLoader.loadfile imports auto.py as a module, and setting autoreload to true invokes restart_async so a process supervisor restarts the service and triggers the import. Successful exploitation executes commands with the privileges of the application service account and can disclose data, modify files, establish persistence, or disrupt the service. Related authorization and registration vulnerabilities can reduce the effective privilege requirement in a chained attack, but the standalone vulnerability requires administrator access. This issue is fixed in version 3.42.0.

The advisory is available at github.com. This vulnerability is handled as CVE-2026-45272 since 05/11/2026. The exploitation is known to be easy. The attack may be launched remotely. Additional levels of successful authentication are required for exploitation. Technical details are known, but there is no available exploit. This vulnerability is assigned to T1059 by the MITRE ATT&CK project.

Upgrading to version 3.42.0 eliminates this vulnerability.
