Last modified

CVE-2022-3509 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. A parsing issue similar to CVE-2022-3171, but with textformat in protobuf-java core and lite versions prior to 3.21.7, 3.20.3, 3.19.6 and 3.16.3 can lead to a denial of service attack. Inputs containing multiple instances of non-repeated embedded messages with repeated or unknown fields causes objects to be converted back-n-forth between mutable and immutable forms, resulting in potentially long garbage collection pauses. EPSS estimates a 0.57% chance of exploitation in the next 30 days.
