Apache Camel is a widely used enterprise integration framework; this RCE via Redis deserialization can compromise backend services and integrations across organizations.
CVE-2026-78165
Unsafe Java deserialization in Camel Spring Redis enabling remote code execution via Redis messages
Is CVE-2026-78165 being exploited?
Not confirmed. CVE-2026-78165 does not appear in CISA's Known Exploited Vulnerabilities catalog, which records only exploitation that has been observed and reported publicly. That is evidence of absence of a report, not evidence the flaw is unattacked.
How severe is CVE-2026-78165?
CVE-2026-78165 is rated High with a CVSS score of 8.8. Severity describes how bad exploitation would be, not how likely it is: pair it with exploitation evidence before deciding what to patch first.
Is there a patch for CVE-2026-78165?
Yes. A fix has been recorded for CVE-2026-78165. The vendor advisory is the authority on the exact fixed version — apply it from there rather than from a summary.
What does CVE-2026-78165 affect?
CVE-2026-78165 affects Apache Camel 2.11.0 - <4.18.5, Apache Camel 4.19.0 - <4.22.1, camel-spring-redis component, RedisTemplate / SpringRedisIdempotentRepository integrations, and 1 further product or version. Confirm the exact affected versions against the vendor advisory before deciding you are exposed.
What should I do about CVE-2026-78165?
Upgrade to 4.23.0 (or 4.22.1/4.18.5); set jdk.serialFilter or use non-Java serializer; restrict Redis access.
Exploitation status reflects CISA's KEV catalog as we last synced it. Check the catalog directly.
An attacker who can publish or read Redis entries can trigger Java deserialization in Camel and execute arbitrary code on affected hosts.
Immediate action required
- affected>= 2.11.0 and < 4.18.5
- affected>= 4.19.0 and < 4.22.1
As published in the CVE Program record. A version outside these ranges is not a statement that it is unaffected — vendors sometimes understate a range, and distribution-backported builds carry upstream numbers that do not reflect what was patched into them.
