CVE-2025-24853 | Apache JSPWiki: Cross-Site Scripting (XSS) in JSPWiki Header Link processing

A carefully crafted request when creating a header link using the wiki markup syntax, which could allow the attacker to execute javascript in the victim's browser and get some sensitive information about the victim. Further research by the JSPWiki team showed that the markdown parser allowed this kind of attack too. Apache JSPWiki users should upgrade to 2.12.3 or later.

User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:N)
Doesn’t really leak secrets in a meaningful way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
