CVE-2026-85439
Command injection in MOOS-IvP alogsplit allows remote code execution via unsanitized pathnames.
Is CVE-2026-85439 being exploited?
Not confirmed. CVE-2026-85439 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 0.25% probability of exploitation in the next 30 days.
How severe is CVE-2026-85439?
CVE-2026-85439 is rated High with a CVSS score of 8.5. Severity describes how bad exploitation would be, not how likely it is: pair it with exploitation evidence before deciding what to patch first.

Yes. A fix has been recorded for CVE-2026-85439. The vendor advisory is the authority on the exact fixed version — apply it from there rather than from a summary.
What does CVE-2026-85439 affect?
CVE-2026-85439 affects MOOS-IvP <= 24.8.1, alogsplit (SplitHandler::handlePreCheckSplitDir). Confirm the exact affected versions against the vendor advisory before deciding you are exposed.
What should I do about CVE-2026-85439?
Apply the upstream patch/commit, restrict alogsplit privileges, and validate/sanitize log path inputs.
Exploitation status reflects CISA's KEV catalog as we last synced it. Check the catalog directly.
Remote code execution: attackers can inject shell metacharacters in log filenames or the --dir parameter to run arbitrary commands as the operator.

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.
