Security Fixes
[GHSA-8j49-mmcx-4mp5] Arbitrary File Read via Path Traversal in ZIP/APK Icon Extraction
The android:icon attribute from an APK manifest was interpolated into file paths without validation, allowing a crafted APK to read arbitrary files from the server. Fixed by adding is_path_traversal() and is_safe_path() guards in find_icon_path_zip. Dependency bump included.
[GHSA-3p54-567p-2wpr] CSRF Checks Not Enforced After Django Middleware Migration
The migration from the deprecated MIDDLEWARE_CLASSES to MIDDLEWARE omitted CsrfViewMiddleware, SecurityMiddleware, and XFrameOptionsMiddleware, leaving CSRF, HSTS, and clickjacking protections silently disabled. All three have been restored to the active MIDDLEWARE tuple. The now-dead MIDDLEWARE_CLASSES block has been removed to prevent future confusion.
[GHSA-x768-8642-mmq9] Zip Bomb Denial of Service via Per-File Size Limit Bypass
The per-file size check in ZIP extraction logged a warning on oversized members but was missing a continue, allowing files exceeding ZIP_MAX_UNCOMPRESSED_FILE_SIZE to be extracted anyway as long as the aggregate limit was not reached. Fixed by adding the missing continue.
[GHSA-95px-34x5-p37h] SSRF Port Restriction Bypass in assetlinks_check
valid_host() was called with only the bare hostname, allowing android:port to be appended afterward without going through port validation, bypassing the HTTP/HTTPS-only restriction. Fixed with a two-layer approach: primary port allowlist check before URL assembly in get_browsable_activities, and a defence-in-depth re-check in _check_url.
Hardening
The hand-rolled safe_extract used os.path.abspath (symlink-blind) instead of os.path.realpath, creating a TOCTOU window where a symlink could redirect extraction outside the destination directory. Replaced with Python 3.12's tarfile.extractall(filter='data') (PEP 706), which rejects symlinks, hardlinks, absolute paths, and traversal members per-member before extraction. A robust realpath-based fallback is included for older Python versions.
Both download_app_data call sites in the iOS dynamic analyser now wrap app_container and tarfile with shlex.quote when building the SSH tar command, as defensive coding hygiene.
Refactoring
is_path_traversal, is_safe_path, clean_filename, cmd_injection_check, is_pipe_or_link, and is_attack_pattern were scattered across utils.py and shared.py. All have been moved to mobsf/MobSF/security.py as the single authoritative location for security primitives.
Developer Tooling
AGENTS.md / CLAUDE.md - AI agent guidelines
Added a coding-standards document for AI coding agents (Cursor, Claude, Codex) covering MobSF-specific secure-by-default patterns: path traversal guards, archive extraction safety, Django middleware active-tuple hygiene, split-validation anti-patterns (SSRF port bypass), guard completeness (continue/return/raise after every security check), and Django-specific security features (form validators, decorators, middleware). CLAUDE.md is a symlink to AGENTS.md.
Enables dynamic analysis on real jailbroken iOS devices connected via USB or WiFi SSH, complementing the existing Corellium-based iOS analysis.
- SSH connectivity — connects to jailbroken devices over USB (via iproxy port forwarding) or WiFi using Paramiko SSH
- Frida instrumentation — spawns/attaches Frida on-device, with full hook support matching the existing Corellium flow
- Environment setup — installs AppSync Unified and Frida server on first run; supports both arm and arm64 devices
- Dynamic analysis — app file extraction, system log streaming (oslog), screenshot capture, process listing, and report generation
- SSH terminal — execute shell commands on the device over SSH

This PR strips out androguard and it's dependencies from MobSF.
Extract androguard related functions used by MobSF.
Some dependencies such as pyQt5 from apkinspector is breaking the ARM64 docker image.
This should address that issue.
In future, we will have to copy over any fixes to axml, apk, public, types from androguard and ZipEntry from apkinspector.
We won't be adding linting to these files. The extracted functions will be considered as an external tool.
