High-severity RCE in widely deployed Adobe enterprise product (Campaign Classic); unauthenticated/low-privilege exploit can disrupt orgs and attract broad attention.
CVE-2026-105780
Authorization bypass in Adobe Campaign Classic allows arbitrary code execution.
Is CVE-2026-105780 being exploited?
Not confirmed. CVE-2026-105780 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-2026-105780?
CVE-2026-105780 is rated Critical with a CVSS score of 9.9. 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-2026-105780?
Not known from our data. No patch reference has been recorded for CVE-2026-105780, which is not the same as no patch existing — a fix may have shipped without a tagged reference, or after this record was written. The vendor advisory is the only authority on whether a fix exists, and mitigations may be available regardless.
What does CVE-2026-105780 affect?
CVE-2026-105780 affects Adobe Campaign Classic (ACC). Confirm the exact affected versions against the vendor advisory before deciding you are exposed.
What should I do about CVE-2026-105780?
Apply vendor patch immediately; if unavailable, isolate ACC, restrict access, and monitor logs.
Exploitation status reflects CISA's KEV catalog as we last synced it. Check the catalog directly.
Incorrect authorization enables arbitrary code execution as the current user; low-priv attacker, no user interaction, enabling system compromise and lateral movement.

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.
