Prior to version 0-PRERELEASE-15, the vote API route (`POST \/api\/v1\/forum\/vote`) trusts the JSON body\u2019s `direction` value without runtime validation. TypeScript types are not enforced at runtime, so an attacker can send arbitrary strings (e.g., `&#8221;x&#8221;`) as `direction`. Downstream (`VoteServer`) treats any non-`&#8221;up&#8221;` and non-`null` value as a downvote and persists the invalid value in `votes_data`. This can be exploited to bypass intended business logic. Version 0-PRERELEASE-15 fixes the vulnerability.<\/p>\n<p>Severity: 7.1 | HIGH<\/p>\n<p>Visit the link for more details, such as CVSS details, affected products, timeline, and more&#8230;\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"<p>CVE ID : CVE-2026-25126 Published : Jan. 29, 2026, 10:15 p.m. | 54\u00a0minutes ago Description : PolarLearn is a free and open-source learning program.
