SCA: security update for io.netty.incubator:netty-incubator-codec-ohttp (GHSA-vmr9-j6wf-pmh2)

high Tenable Cloud Security Plugin ID 446170

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - netty-incubator-codec-ohttp implements Oblivious HTTP (OHTTP) gateway and client functionality using
 Netty. Prior to 0.0.23.Final, the OHTTP gateway decryption path in codec-
 ohttp/src/main/java/io/netty/incubator/codec/ohttp/OHttpRequestResponseContext.java allocates a pooled
 direct ByteBuf for decrypted plaintext before the AEAD tag is verified. When an invalid tag causes
 decryptChunk() to throw CryptoException, OHttpRequestResponseContext.decodeChunk() does not release the
 ByteBuf because the allocation is not guarded by try/finally. Repeated invalid encrypted requests can
 therefore leak native off-heap memory until the gateway is unable to continue serving requests. This issue
 is fixed in version 0.0.23.Final. (CVE-2026-54251)

Solution

Update the io.netty.incubator:netty-incubator-codec-ohttp library and its related packages to version 0.0.23.Final or later.
