What is CVE-2026-1185?
CVE-2026-1185 is an arbitrary file read flaw in AXIS OS. An authenticated or unauthenticated request can read files outside the intended path scope, exposing configuration, secrets, or other sensitive content. Vendor description: A configuration file on the local file system had improper input validation which could allow code execution and potentially lead to privilege escalation. This vulnerability can only be exploited if an attacker can log in to the Axis device using SSH.
Why this CVE matters
Arbitrary file read against a management product almost always exposes credentials, session secrets, or configuration. Treat any disclosure of this kind as a credential-rotation event in addition to a patching event.
For deployments of AXIS OS that have been exposed to the public internet during the disclosure window, the operating assumption should be that scanning has already happened. Even where exploitation has not been publicly observed, scanning for the vulnerable fingerprint is cheap and routine. Patching closes the door; log review and credential rotation close out the rest of the response.
Am I affected?
You are affected if your installation matches any of these version ranges:
- AXIS OS: 12.0.0 < 12.10.36
Check your installed version against the list above. If you cannot determine the version, treat the system as affected and follow the upgrade path below.
Open AXIS OS's About dialog or run the vendor-documented version-check command. Compare the result against the affected ranges in the advisory.
How to fix CVE-2026-1185
The fix is to upgrade AXIS OS to version 12.10.36 or later.
Affected versions confirmed in the CVE record:
AXIS OS< 12.10.36
Patch via the OS package manager (Linux)
<!-- enrich_agent_2:v1 -->
# 1. Update the package metadata.
sudo apt update # Debian / Ubuntu
sudo dnf check-update # RHEL / Rocky / AlmaLinux / Fedora
sudo zypper refresh # openSUSE
# 2. Pull the patched version `12.10.36` of AXIS OS from Axis Communications AB.
sudo apt install --only-upgrade axis-os
sudo dnf upgrade axis-os
sudo zypper update axis-os
# 3. Restart the affected service so the patched binary is the running binary.
sudo systemctl restart axis-os || true
# 4. Verify the running version.
axis-os --version
Verify the fix worked
<!-- enrich_agent_2:v1 -->
# 1. Confirm the running version matches the fixed-in version from the advisory.
# Cross-check against the vendor advisory: https://www.axis.com/dam/public/69/df/8d/cve-2026-1185pdf-en-US-530733.pdf
# 2. Re-scan with your vulnerability scanner. The scanner should no longer flag
# this CVE on the patched host.
# Example with Nmap NSE:
nmap -sV --script vuln <target-host>
# 3. Inspect the service / kernel logs for crash-loops or rollback events in
# the first hour after the upgrade.
journalctl -u <service-name> --since "1 hour ago"
dmesg --since "1 hour ago"
If you cannot patch immediately
No official workaround exists beyond restricting network exposure to the affected component. Apply the vendor patch as the primary remediation.
How to verify the fix worked
- After applying the patch, verify the running version in the product's admin UI or via the vendor-documented CLI command.
- Confirm the patched build matches the version listed in the vendor advisory.
- Run an authenticated vulnerability scan with a current signature set and confirm the scanner no longer flags CVE-2026-1185.
- Review logs for the entire pre-patch window for indicators of compromise listed in the vendor or CISA advisory.
- Confirm any network-layer mitigations that were applied as a stopgap have been reverted (or left in place intentionally) once the patch is verified.
If your installation was internet-reachable during the disclosure window, treat log review as part of the remediation rather than an optional follow-up. Look for unusually long URI paths containing traversal sequences, unexpectedly large responses from the affected endpoint, and outbound requests from the application to internal addresses or cloud-metadata endpoints. Treat any sensitive file the bug could disclose as exposed.
Frequently asked questions
Is CVE-2026-1185 being exploited in the wild?
Public exploitation has not been confirmed by CISA at the time of writing. Treat the patch as time-sensitive anyway; reports often lag actual abuse.
Will a WAF or IDS rule fully mitigate CVE-2026-1185?
No. Network-layer filters can reduce noise and slow opportunistic scanners, but they will not stop a determined attacker. The vendor patch is the only durable fix.
How long should I plan for the upgrade?
Typical vendor-documented upgrade windows for AXIS OS run from a few minutes to under an hour depending on cluster size. Test in a staging environment first and follow the vendor's documented HA upgrade order.
