Improper Handling of Highly Compressed Data (Data Amplification)

Overview Affected versions of this package are vulnerable to Improper Handling of Highly Compressed Data Data Amplification through the JWE decompression that has no upper limit for plaintext size. An attacker can exhaust system memory by sending specially crafted compressed tokens that decompres...

GHSA-FJRM-76X2-C4Q4 JWCrypto: JWE ZIP decompression bomb

Summary The fix for GHSA-j857-7rvv-vj97 in v1.5.6 is weak in that it does not allow to fully control the amount of plaintext the receiver is willing to deal with and provides just a weak upper bound. The patch limits input token size to 250KB but does not validate the decompressed output size. An...
