CVE-2026-1603: An authentication bypass in Ivanti Endpoint Manager before version 2024 SU5 allows a remote unauthenticated attacker to leak specific stored

Noroxi assessment

Priority: Now (action score 87/100)

  • CISA has confirmed exploitation in the wild (Mar 9, 2026). Remediation deadline for US federal agencies: Mar 23, 2026.
  • A ready-made attack module is public (Nuclei); exploiting it takes no special expertise.
  • Probability of exploitation in the next 30 days: 88.3% (FIRST EPSS); higher than 99.7% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • According to the record, no fixed version is available yet.

Patch today or shut off access. Until a fix is released, restrict access to the affected component and follow the vendor's advisory.

Actively exploited in the wild

CISA added this to its Known Exploited Vulnerabilities catalog on Mar 9, 2026. That signals real attacks, not theory.

Remediation deadline for US federal agencies: Mar 23, 2026.
