95b4c1500001 is described below

commit 95b4c1500001bc32877df5b8fca0bc7bdd080666
Author: Andrea Cosentino <[email protected]>
AuthorDate: Mon Aug 31 18:17:31 2026 +0200

    CAMEL-24437/24439/24441/24443/24454: secure-default fixes, backport to 
camel-4.22.x
    
    Backports five fixes already reviewed and merged on main, grouped together 
because
    each changes a default or adds a check that was not there before. 
camel-mllp stops
    logging HL7 payload content unless logPhi=true is set explicitly (previously
    defaulted to on, and two paths logged regardless of the setting). 
camel-knative
    with SSL enabled but no truststore configured no longer falls back to 
trusting
    every certificate; a deliberate trust.all property restores the old 
behaviour.
    camel-oauth now binds the authorization-code callback to the flow that 
started it
    via a random state parameter, checked with a constant-time comparison, 
closing a
    login-CSRF gap. camel-shiro verifies presented credentials on every exchange
    instead of accepting a subject already bound to the thread when
    alwaysReauthenticate=false. camel-crypto-pgp rejects decryption of a 
message with
    no integrity-protection packet unless requireIntegrityProtection=false is 
set.
    
    All five are straight cherry-picks, applied in main merge order. One 
mechanical
    adaptation: the new cases in OAuthProcessorFailClosedTest use JUnit 
assertions,
    since camel-oauth has no assertj test dependency on this branch. 
Upgrade-guide
    entries are intentionally excluded — those live on main only.

    Closes #25944
