PYSEC-2026-3851 icalendar has Algorithmic Complexity in Equality
Summary Component.eq compares subcomponents in O2^n time relative to nesting depth. Because the parser accepts arbitrarily nested components, a sub-kilobyte .ics file is enough to make a single equality check run for minutes or hang indefinitely. Any application that compares parsed components ==...

CVE-2026-55099
icalendar is an RFC 5545 compatible parser and generator of iCalendar files for Python. From 7.1.0 until 7.1.3, the Component equality method in src/icalendar/cal/component.py compares nested subcomponents with two membership loops, and each membership test invokes the same method on child...

CVE-2026-55099
icalendar is an RFC 5545 iCalendar parser and generator for Python. In versions 7.1.0 through 7.1.3 , the Component equality method in src/icalendar/cal/component.py compares nested subcomponents using two membership loops that recursively invoke the same method on child components, producing O(2...
