LowCVSS 3.7Exploitation Probability (EPSS)
Low risk26th percentile - higher than 26% of all known CVEs
Summary
A weakness was identified in pkp-lib versions 3.3.0, 3.4.0, and 3.5.0. It affects the setData function in the file classes/user/form/APIProfileForm.php, related to API Key Generation. Manipulation of the apiKey argument leads to insufficient entropy. The attack can be performed remotely but has high complexity and is difficult to exploit. A patch is available with ID 529b5df878e571ccc727647f7748eafc1466b041.
Risk Assessment
The risk involves the possibility of predicting or guessing API keys, which could allow unauthorized access to the system or data. Due to the high complexity of the attack, the risk is moderate but still significant.
Recommendation
It is recommended to apply the available patch (529b5df878e571ccc727647f7748eafc1466b041) and update pkp-lib to the latest version to ensure adequate entropy of generated keys.
