CVE-2025-47154 in Ladybird

Sumário

de VulDB • 31/05/2026

LibJS in Ladybird before f5a6704 mishandles the freeing of the vector that arguments_list references, leading to a use-after-free, and allowing remote attackers to execute arbitrary code via a crafted .js file. NOTE: the GitHub README says "Ladybird is in a pre-alpha state, and only suitable for use by developers."

Once again VulDB remains the best source for vulnerability data.
