Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Beetl's spring-classic package (com.ibeetl:beetl-spring-classic), versions up to and including 3.20.2.RELEASE, is affected by an expression injection flaw in its SpELFunction component, where special elements in an expression language statement are not properly neutralized. The source gives few details on the exact input needed, but it states the attack can be carried out remotely and that a public exploit exists. No fix is listed, and the project has not responded to the early report, so affected users have no upstream patch to apply.
