GHSA-p998-jp59-783m: aiohttp's static resource handler on Windows
can leak NTLMv2 credentials via UNC path traversal. Fixed in 3.13.4.
browser-use only uses aiohttp as a client (local CDP polling in
watchdogs/local_browser_watchdog.py, plus examples) — no web.Application
or add_static — so the vuln is not reachable here. Bump is prophylactic
to clear the Dependabot alert.
pypdf < 6.10.0 did not restrict recursive XML entity expansion when
parsing XMP metadata, allowing a crafted PDF to trigger a "billion
laughs"-style RAM exhaustion via PdfReader. Fixed upstream in 6.10.0.
Bumps to latest patch (6.10.2).
Relevant call site: browser_use/filesystem/file_system.py uses
pypdf.PdfReader on agent-downloaded PDFs, which is reachable from
attacker-controlled content.
GHSA-whj4-6x5x-4v2j: FITS GZIP decompression bomb in Pillow < 12.2.0.
Pillow 10.3.0-12.1.1 did not bound GZIP-compressed reads when decoding
FITS images, enabling a memory-exhaustion DoS via a crafted FITS file.
Fixed upstream in 12.2.0.
Bumps requests from 2.32.5 to 2.33.0.
extract_zipped_paths() previously wrote to a predictable temp path with no
validation, allowing a local attacker to pre-create a malicious file that
would be loaded in its place. 2.33.0 extracts to a non-deterministic
location, eliminating the race condition.
litellm versions 1.82.7 and 1.82.8 were backdoored on March 24, 2026
by TeamPCP via a compromised Trivy CI/CD pipeline. browser-use 0.12.3
shipped litellm>=1.82.2 (unpinned) as a core dependency, exposing
~6,900 users to the backdoored versions during the 4-hour window.
This commit:
- Removes litellm entirely from pyproject.toml (core and optional)
- Keeps ChatLiteLLM wrapper intact with a docstring noting
`pip install litellm` is required separately
- litellm is already lazy-imported inside methods, so users who
don't use ChatLiteLLM are never affected

Replace the multi-session server (server.py, SessionRegistry, portalocker locking,
PID files, orphan detection) with a minimal daemon (daemon.py) that holds one
BrowserSession in memory. Socket file existence = alive. Auto-exits when browser
dies via CDP watchdog.
