CVE-2026-85243
Description
A flaw was found in the Apache Camel Crypto PGP (Pretty Good Privacy) component. A remote attacker capable of intercepting or altering network traffic can tamper with encrypted messages without detection by sending legacy data packets that omit integrity protection. This issue occurs because the decryption process does not enforce integrity checks on older packet formats. Consequently, the receiving application may accept and process modified data under the assumption that it is authentic.
Statement
This vulnerability is rated as having Moderate impact for Red Hat products because tampering requires an attacker to be positioned to intercept and manipulate message traffic, and exploitation only affects services that actively ingest and decrypt PGP-formatted data. In Red Hat build of Apache Camel and JBoss Fuse environments, the Camel Crypto PGP data format is not enabled by default and requires explicit inclusion in integration routes. Although legacy encrypted packets lacking modification detection codes can be silently altered, the vulnerability does not directly expose secret keys or enable remote execution.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.

Understanding the Weakness (CWE)
Integrity,Other
Technical Impact: Modify Application Data; Other
Integrity checks usually use a secret key that helps authenticate the data origin. Skipping integrity checking generally opens up the possibility that new data from an invalid source can be injected.
Integrity,Other
Technical Impact: Other
Data that is parsed and used may be corrupted.
Non-Repudiation,Other
Technical Impact: Hide Activities; Other
Without a checksum check, it is impossible to determine if any changes have been made to the data after it was sent.
