Information disclosure via incorrect array hole handling
Published Jul 7, 2023 · Updated Nov 13, 2024
Information disclosure in JerryScript 3.0.0 allows remote attackers to read sensitive data by submitting a crafted array script. Array-literal spread handling incorrectly skips a trailing empty element, producing a shorter array, but the public evidence does not demonstrate the reported out-of-bounds read or identify exposed data. Reachability depends on an embedding application accepting attacker-controlled JavaScript, and the available record does not establish which memory contents can be read.
