What is CVE-2024-45296?

The path-to-regexp library, used to convert path strings into regular expressions, has a vulnerability that can lead to performance degradation. This occurs when a specific formatting of parameters is used, resulting in a complex regular expression that could monopolize the JavaScript main thread. As JavaScript operates in a single-threaded environment, this regex-induced slowdown can block the event loop, potentially leading to a denial of service condition. Users employing version 0.1 of the library should upgrade to 0.1.10, while all other versions should be updated to 8.0.0 to mitigate these performance risks.

Human OS v1.0:
Ageing Is an Unpatched Zero-Day Vulnerability.

Remediate biological technical debt. Prime Ageing uses 95% high-purity SIRT6 activation to maintain genomic integrity and bolster systemic resilience.
