CVE-2026-24490 — MobSF has Stored XSS via Manifest Analysis - Dialer Code Host Field

MobSF is a mobile application security testing tool used. Prior to version 4.4.5, a Stored Cross-site Scripting (XSS) vulnerability in MobSF's Android manifest analysis allows an attacker to execute arbitrary JavaScript in the context of a victim's browser session by uploading a malicious APK. The `android:host` attribute from `<data android:scheme="android_secret_code">` elements is rendered in HTML reports without sanitization, enabling session hijacking and account takeover. Version 4.4.5 fixes the issue.

Low

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.

How the score was calculated

EPSS 0.4% (30-day exploitation probability)+4
Technical severity (medium)+3
CISA SSVC: exploitation "poc"+5

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Exploitation

Not confirmed

Not in CISA KEV — an absence of record, not proof it is unexploited.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

Documented patch — github.com (NIST National Vulnerability Database)

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

Identify exposed assets running the affected vendor/product/version combinations (MobSF Mobile-Security-Framework-MobSF, Opensecurity Mobile Security Framework).
Apply the fixed version or the patch documented under Remediation.
Exploitation requires user interaction: tighten email/web filtering and warn affected users.
Search available logs for exploit probes matching the vulnerability class (cross-site scripting), errors and authentication anomalies.

What should defenders know first?

CVE-2026-24490 is "MobSF has Stored XSS via Manifest Analysis - Dialer Code Host Field", rated Medium. It affects Mobile-Security-Framework-MobSF (MobSF); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 4.8 describes technical severity. EPSS 0.35% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
