CVE-2026-112041: Cryptographically Weak PRNG in diem-project diem
Description
CVE-2026-112041 is a medium severity vulnerability in the diem-project diem software involving a cryptographically weak pseudorandom number generator (PRNG) in the dmString::random function. The vulnerability affects versions up to commit 116974edfb9a5b8bd69cb13586dc62bcdbb485ad. Exploitation requires high complexity and no privileges or user interaction, and the exploit is publicly available. The project uses a rolling release system, so specific affected or fixed versions are not disclosed. The vendor has not yet responded or provided a patch.

Technical Analysis
This vulnerability in diem-project diem affects the dmString::random function in dmCorePlugin/lib/basic/dmString.php, resulting in a cryptographically weak PRNG. The weakness could be exploited remotely, though with high complexity and difficult exploitability. The exploit code is publicly available. Due to the rolling release model, no explicit version ranges are provided. The vendor has been informed but has not issued a fix or advisory.
Potential Impact
The cryptographically weak PRNG may reduce the randomness quality used by the application, potentially weakening cryptographic operations relying on it. However, the attack complexity is high, and no privileges or user interaction are required. The vulnerability could be leveraged remotely, but no active exploitation in the wild is known. The impact is rated medium severity with a CVSS 4.0 score of 6.3.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since the vendor has not responded or released a fix, users should monitor official channels for updates. Until a patch is available, consider mitigating risks by limiting exposure of affected functionality and reviewing cryptographic usage if possible.
