The vulnerability stems from improper output sanitization in warning message handling during file imports. The commit diff shows the fix added Message::sanitize() to the $warning parameter in this function. Before the patch, the raw $warning input (from imported files) was passed to Message::notice() and rendered via getDisplay(), enabling HTML/script injection. This matches the described XSS vulnerability pattern where user-controlled input isn't properly neutralized before web page generation.
