What is CVE-2026-44548?

CVE-2026-44548 is a cross-site request forgery (csrf) in CRM. ChurchCRM is an open-source church management system. Prior to 7.3.2, top-level cross-site GET navigation from an attacker-controlled page to FundRaiserDelete.php, PropertyTypeDelete.php, or NoteDelete.php causes a logged-in ChurchCRM user with the relevant role to silently delete records, including cascaded property and record-to-property assignments. Full technical detail is in the vendor advisory and the NVD entry.

Why this CVE matters

The cross-site request forgery (csrf) class of flaw against CRM 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 php 2>/dev/null | grep -i version    # Debian / Ubuntu
rpm -q php 2>/dev/null                       # RHEL / Rocky

How to fix CVE-2026-44548

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/ChurchCRM/CRM/security/advisories/GHSA-jx5r-p82p-2p8m
# Update to the patched release named in the advisory
npm install crm@latest
# or pin to the exact fixed version from the vendor advisory
npm install crm@<patched-version>
npm ls crm

PyPI (pip / Poetry)


# Vendor advisory: https://github.com/ChurchCRM/CRM/security/advisories/GHSA-jx5r-p82p-2p8m
pip install --upgrade crm
pip show crm | grep -i version
# Poetry:
poetry add crm@^<patched-version>

Docker / container


# Vendor advisory: https://github.com/ChurchCRM/CRM/security/advisories/GHSA-jx5r-p82p-2p8m
docker pull <your-registry>/crm:<patched-tag>
docker stop <app> && docker rm <app>
docker run -d --name <app> <your-registry>/crm:<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.


# No vendor-published workaround for CVE-2026-44548 beyond the patch.
# Reduce the blast radius until the patched build is deployed:
#   - Restrict network access to the affected service to known admin hosts
#   - Disable the vulnerable feature in config if the product allows it
#   - Increase logging on the affected endpoints and watch for IoCs

How to verify the fix worked

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


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

Run an authenticated vulnerability scan with a current signature set and confirm the scanner no longer flags CVE-2026-44548. 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.

Frequently asked questions

Is CVE-2026-44548 being exploited in the wild?

At time of writing, CVE-2026-44548 is not on CISA's KEV list. 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.

What is the CVSS score for CVE-2026-44548?

The CVSS base score is 8.1 (High). Full vector detail is on the NVD entry.

Will a firewall rule or WAF signature fully mitigate CVE-2026-44548?

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.

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.
