CVE-2026-55771
Logic bug in CedarJava equals() causes incorrect entity ID comparisons.
Is CVE-2026-55771 being exploited?
Not confirmed. CVE-2026-55771 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. EPSS currently estimates a 0.57% probability of exploitation in the next 30 days.
How severe is CVE-2026-55771?
CVE-2026-55771 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-2026-55771?
Yes. A fix has been recorded for CVE-2026-55771. The vendor advisory is the authority on the exact fixed version — apply it from there rather than from a summary.
What does CVE-2026-55771 affect?
CVE-2026-55771 affects CedarJava < 4.9.0, Java applications using CedarJava EntityIdentifier.equals(). Confirm the exact affected versions against the vendor advisory before deciding you are exposed.
What should I do about CVE-2026-55771?
Upgrade to CedarJava 4.9.0 and audit equality/comparison usage.
Exploitation status reflects CISA's KEV catalog as we last synced it. Check the catalog directly.
Inverted equals() null/self logic can cause incorrect equality checks, potentially enabling authorization bypass or incorrect access decisions in integrator Java apps.
Patch when possible
- affected< 4.9.0
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.
