How to Fix CVE-2026-42185: Improper Privilege Management in people

Q: Is CVE-2026-42185 being exploited in the wild?

At time of writing, CVE-2026-42185 is not on [CISA's KEV list](https://www.cisa.gov/known-exploited-vulnerabilities-catalog). Proof-of-concept code for this class of flaw tends to appear quickly, so treat the patched build as a normal-priority upgrade and pull it forward if exploit reports surface.

Q: What is the CVSS score for CVE-2026-42185?

The CVSS base score is 5.5 (Medium). Full vector detail is on the [NVD entry](https://nvd.nist.gov/vuln/detail/CVE-2026-42185).

Q: Will a firewall rule or WAF signature fully mitigate CVE-2026-42185?

No. Network-layer filters slow opportunistic scanners and block a subset of payloads, but a focused attacker who knows the bug will work around them. The vendor patch is the only durable fix.

Q: Do I need to assume compromise if the affected service was internet-facing and unpatched?

Not automatically, but log review is cheap insurance. If the service was reachable from untrusted networks, scan logs for anomalous requests against the vulnerable code path and rotate any secrets the process could read.

What is CVE-2026-42185?

CVE-2026-42185 is a improper privilege management in people. People is an application to handle users and teams, and distribute permissions across La Suite. Prior to version 1.25.0, a user holding the Administrator role on a mail domain could send a crafted invitation request to promote any existing user (including users with no current domain access) to the Owner role. Full technical detail is in the vendor advisory and the NVD entry.

Why this CVE matters

The improper privilege management class of flaw against people is the kind of issue attackers chain into broader access once they get a foothold. Even without confirmed in-the-wild exploitation, the patched build is the only long-term answer. Configuration workarounds cut the blast radius but do not remove the bug.

Am I affected?

Run the version check that matches your platform. If the installed build sits inside the affected range from the table above, the fix applies to you.


# Linux package check
dpkg -s people 2>/dev/null | grep -i version    # Debian / Ubuntu
rpm -q people 2>/dev/null                       # RHEL / Rocky

How to fix CVE-2026-42185

Apply the patched build the vendor names in the advisory. The commands below are starting points keyed to common platforms; adapt the package name and target version to your environment.

npm / Yarn / pnpm


# Vendor advisory: https://github.com/suitenumerique/people/security/advisories/GHSA-42cf-rv2h-v8rf
# Update to the patched release named in the advisory
npm install people@latest
# or pin to the exact fixed version from the vendor advisory
npm install people@<patched-version>
npm ls people

PyPI (pip / Poetry)


# Vendor advisory: https://github.com/suitenumerique/people/security/advisories/GHSA-42cf-rv2h-v8rf
pip install --upgrade people
pip show people | grep -i version
# Poetry:
poetry add people@^<patched-version>

Docker / container


# Vendor advisory: https://github.com/suitenumerique/people/security/advisories/GHSA-42cf-rv2h-v8rf
docker pull <your-registry>/people:<patched-tag>
docker stop <app> && docker rm <app>
docker run -d --name <app> <your-registry>/people:<patched-tag>

After the upgrade, restart any service that loads the patched binary so the new code is actually running.

If you can't patch immediately

Patching is the only durable fix. These mitigations cut exposure while the change window is scheduled. They do not remove the vulnerability.

Restrict network exposure (iptables / nftables)


# Replace 10.0.0.0/8 with your management network.
sudo iptables -I INPUT -p tcp --dport 443 -s 10.0.0.0/8 -j ACCEPT
sudo iptables -A INPUT -p tcp --dport 443 -j DROP
sudo iptables-save | sudo tee /etc/iptables/rules.v4


# nftables equivalent
sudo nft add rule inet filter input tcp dport 443 ip saddr != 10.0.0.0/8 drop

Web server / WAF rule (ModSecurity sample)


# Append to /etc/modsecurity/rules/local.conf and reload Apache.
SecRule REQUEST_URI "@rx (?:\.\./|%2e%2e/)" \
    "id:900001,phase:1,deny,status:403,msg:'Path traversal attempt blocked'"
SecRule ARGS "@rx (?:union[\s/*]+select|select[\s/*]+.*from)" \
    "id:900002,phase:2,deny,status:403,msg:'SQLi pattern blocked'"


sudo systemctl reload apache2    # or nginx

How to verify the fix worked

After applying the patched build, confirm the version string matches the fixed release named in the suitenumerique advisory.


dpkg -s people | grep -i version       # Debian / Ubuntu
rpm -q people                          # RHEL / Rocky

Run an authenticated vulnerability scan with a current signature set and confirm the scanner no longer flags CVE-2026-42185. For internet-facing deployments that were unpatched during the disclosure window, review logs for the affected endpoints over the full exposure period and rotate any credentials the vulnerable process could touch.
