Short explanation
An improper validation of integrity check value vulnerability in the Apache Camel Crypto PGP component allows attackers or in-transit actors to bypass integrity protection. Affected versions include Apache Camel from 4.0.0 before 4.18.5 and from 4.19.0 before 4.22.1.
This vulnerability enables the bypass of integrity checks on encrypted messages, leading to compromised data integrity and allowing attackers to manipulate payloads.
What should be done?
- Upgrade to Apache Camel 4.23.0
- Upgrade 4.18.x users to 4.18.5
- Upgrade 4.22.x users to 4.22.1

Show the technical text from the sources
Improper Validation of Integrity Check Value vulnerability in Apache Camel Crypto PGP component. This issue affects Apache Camel: from 4.0.0 before 4.18.5, from 4.19.0 before 4.22.1. unmarshal() verified the modification detection code only when the message was an OpenPGP symmetrically encrypted integrity protected data packet. The older symmetrically encrypted data packet carries no such code, and OpenPGP's CFB mode is malleable without one, so a message using that packet skipped the check altogether. The packet type is chosen by whoever produced the message, which left the sender - or anyone able to rewrite the message in transit - deciding whether the integrity check applied at all. The existing integrity option governs marshalling only and had no decrypt-side counterpart, so a deployment could not require integrity protection on the messages it accepted. Upgrade to Apache Camel 4.23.0, which fixes the issue. Users on the 4.18.x LTS releases stream should upgrade to 4.18.5. Users on the 4.22.x LTS releases stream should upgrade to 4.22.1. A requireIntegrityProtection option, defaulting to true, now rejects a message that is not integrity protected. Note that signatureVerificationOption still defaults to optional, so a message carrying no signature is accepted; the two options together are what give a decrypted message authenticity and not only confidentiality. For deployments that cannot upgrade immediately, reject messages that do not use the integrity protected packet before they reach the data format. Routes that must interoperate with a sender still emitting the legacy packet should set requireIntegrityProtection=false after upgrading, and treat the decrypted content as unauthenticated.
