CVE-2026-19906: Insufficient Entropy in pkp pkp-lib
CVE-2026-19906 is a medium severity vulnerability in pkp-lib versions 3.3.0, 3.4.0, and 3.5.0. It involves insufficient entropy in the API Key Generation component, specifically in the setData function of classes/user/form/APIProfileForm.php. The vulnerability can be triggered by manipulating the apiKey argument remotely, but exploitation is considered difficult due to high complexity. A patch identified by commit 529b5df878e571ccc727647f7748eafc1466b041 is recommended to resolve the issue.
AI Analysis
Technical Summary
This vulnerability affects the pkp-lib software library versions 3.3.0, 3.4.0, and 3.5.0. It arises from insufficient entropy in the API Key Generation process, specifically within the setData function of the APIProfileForm.php file. An attacker can manipulate the apiKey argument remotely to cause this weakness. The attack complexity is high, and no privileges or user interaction are required. The CVSS 4.0 base score is 6.3, indicating medium severity. The vulnerability has not been reported as exploited in the wild. A patch exists identified by commit 529b5df878e571ccc727647f7748eafc1466b041, and applying it is best practice.
Potential Impact
The vulnerability could reduce the randomness (entropy) of generated API keys, potentially weakening their security. This could allow an attacker to predict or guess API keys more easily, undermining authentication or authorization mechanisms relying on these keys. However, the attack complexity is high, and no known exploits are reported in the wild, limiting immediate risk.
Mitigation Recommendations
A patch identified by commit 529b5df878e571ccc727647f7748eafc1466b041 is available and should be applied to affected versions 3.3.0, 3.4.0, and 3.5.0 of pkp-lib. Since the vendor advisory or patch details are not explicitly provided, confirm patch availability and installation instructions from the official pkp project resources. No alternative mitigations are specified.
