Caveat: Will update by re-generating file.

Important

pip-licenses is NOT impacted by CVE-2026-4539 for normal use-cases. pip install pip-licenses>=5 will not install the affected developer package Pypgments; Most users should be unaffected.

Caution

Developers: may however want to ensure their version of Pypgments to 2.20+ (e.g., fixed versions) to avoid any possible performance impact when testing from the CVE-2026-4539 reDoS.
