What is CVE-2026-33545?

CVE-2026-33545 is a SQL injection flaw in Mobile-Security-Framework-MobSF. User input reaches a database query without proper parameterization, letting an attacker read, modify, or in some cases execute commands through stacked queries or out-of-band channels. Vendor description: MobSF is a mobile application security testing tool used. Prior to version 4.4.6, MobSF's read_sqlite() function in mobsf/MobSF/utils.py (lines 542-566) uses Python string formatting (%) to construct SQL queries with table names read from a SQLite database's sqlite_master table.

Why this CVE matters

SQL injection against a management product is rarely just a data leak. Once an attacker can read or write to the application database, the chain commonly ends with credential theft, persistence via scheduled tasks, or stacked queries that pivot into the operating system.

For deployments of Mobile-Security-Framework-MobSF 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:

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 Mobile-Security-Framework-MobSF'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-2026-33545

  1. Read the vendor advisory in full: https://github.com/MobSF/Mobile-Security-Framework-MobSF/security/advisories/GHSA-hqjr-43r5-9q58
  2. Upgrade Mobile-Security-Framework-MobSF to the patched build listed in the vendor advisory.
  3. Back up the configuration (and database, where applicable) before upgrading.
  4. Rotate any credentials, API keys, or session tokens that the vulnerable service touched. An unauthenticated RCE-class flaw means anything the process could see should be treated as exposed.
  5. Apply the patch in a maintenance window. For HA pairs, upgrade the standby node first, fail over, then upgrade the former primary.
  6. Restart the affected service so the patched binary loads, then verify the new version (see verification section).

Update the Python package mobile-security-framework-mobsf to 4.4.6

Vendor advisory: https://github.com/MobSF/Mobile-Security-Framework-MobSF/security/advisories/GHSA-hqjr-43r5-9q58


# Patch in-place.
python -m pip install --upgrade "mobile-security-framework-mobsf>=4.4.6"

# For projects pinned via requirements.txt, bump the pin and re-sync.
sed -i 's/^mobile-security-framework-mobsf==.*/mobile-security-framework-mobsf==4.4.6/' requirements.txt
python -m pip install -r requirements.txt

# Verify.
python -m pip show mobile-security-framework-mobsf | grep Version


# Same flow on Windows.
python -m pip install --upgrade "mobile-security-framework-mobsf>=4.4.6"
python -m pip show mobile-security-framework-mobsf

Verify the fix landed


# Vendor advisory: https://github.com/MobSF/Mobile-Security-Framework-MobSF/security/advisories/GHSA-hqjr-43r5-9q58
# 1. Confirm the running version matches the fixed-in version listed above.

# 2. Re-scan with your vulnerability scanner (Nessus, Qualys, Tenable, OpenVAS).
#    The scanner should no longer flag this CVE on the patched target.

# 3. Inspect recent service / kernel logs for crash-loops or rollback events.

If you cannot patch immediately

Front the affected endpoint with a WAF rule that blocks SQL metacharacters in the vulnerable parameters. This is a stopgap, not a fix. Patch promptly.

How to verify the fix worked

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 unexpected administrator accounts in Mobile-Security-Framework-MobSF, scheduled tasks or cron jobs you did not create, new files in web-accessible directories, and outbound connections to addresses not in your baseline. Suspicious requests to the vulnerable endpoint immediately followed by successful 200-class responses with unusually large bodies are a strong indicator of exploitation.

Frequently asked questions

Is CVE-2026-33545 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-2026-33545?

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.

Do I need to assume compromise if my Mobile-Security-Framework-MobSF was internet-facing and unpatched?

For an unauthenticated RCE-class flaw exposed to the public internet during the known exploitation window, yes. Review logs, rotate credentials the process could access, and look for unexpected accounts, scheduled tasks, or outbound connections.
