CVE-2026-78701: 389-ds-base: 389-ds-base: cve-2026-11610 incomplete fix may introduce a connection-stall dos

Noroxi assessment

Priority: Monitor (action score 26/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.77% (FIRST EPSS); higher than 55.6% of all records.
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: 389-ds-base (AlmaLinux:10) 3.2.0-10.el10_2; 389-ds-base-bdb (AlmaLinux:10) 3.2.0-10.el10_2; 389-ds-base-devel (AlmaLinux:10) 3.2.0-10.el10_2.

Low priority for now. Upgrade to 389-ds-base (AlmaLinux:10) 3.2.0-10.el10_2; 389-ds-base-bdb (AlmaLinux:10) 3.2.0-10.el10_2; 389-ds-base-devel (AlmaLinux:10) 3.2.0-10.el10_2 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

A flaw was found in 389-ds-base. A remote, authenticated attacker could exploit a vulnerability in the Simple Authentication and Security Layer (SASL) UNBIND process. By sending a specially crafted request, the attacker can cause a connection to stall, leading to resource exhaustion and a Denial of Service (DoS) for the server.
