CVE-2026-13577
Description
A flaw was found in Dancer2. When Cryptographically Secure PseudoRandom Number Generator (CSPRNG) modules are not available, Dancer2 generates insecure session identifiers (IDs). This occurs because the system falls back to using a less secure, built-in random number generator. An attacker could exploit these predictable session IDs to gain unauthorized access to systems.

Understanding the Weakness (CWE)
Other
Technical Impact: Varies by Context
This weakness could be exploited by an attacker in a number ways depending on the context. If a predictable number is used to generate IDs or keys that are used within protection mechanisms, then an attacker could gain unauthorized access to the system. If predictable filenames are used for storing sensitive information, then an attacker might gain access to the system and may be able to gain access to the information in the file.
