What is CVE-2025-47951?

Weblate, a web-based localization tool, experienced a security issue prior to version 5.12 where the verification process for the second factor lacked proper rate limiting. This vulnerability allowed attackers with valid credentials to automate the guessing of one-time passwords (OTPs) due to unrestricted repeated attempts. The issue has been addressed in version 5.12, which implements necessary rate limiting to bolster security against such automated attacks.
