CVE-2010-1128

MediumCVSS 6.4/10Last modified Jun 16, 2026

Description

The Linear Congruential Generator (LCG) in PHP before 5.2.13 does not provide the expected entropy, which makes it easier for context-dependent attackers to guess values that were intended to be unpredictable, as demonstrated by session cookies generated by using the uniqid function.
