CVE-2026-86995 n8n: Git Node branch.<name>.remote Config Key Bypasses Sandbox Path Restriction, Enabling Local Git Repository Read

n8n is an open source workflow automation platform. Prior to 1.123.76, 2.37.7, and 2.38.2, the Git node validated the repository parameter for fetch or pull, but setUpstream wrote a branch..remote value into repository configuration without validating it. A later fetch or pull resolved the remote...

GHSA-8M3C-C648-2XJJ Nodemailer: resolveContent() on a MailMessage bypasses disableFileAccess/disableUrlAccess when called with the legacy signature

Summary Nodemailer's disableFileAccess / disableUrlAccess options are a security sandbox that lets an application forbid untrusted message content html/text/attachment path/href from reading local files or making outbound HTTPS requests. The fix for GHSA-wqvq-jvpq-h66f commit 5f69497 threaded the...

CVE-2026-82533 DeepSeek Harness < 0.1.2-alpha.1 Authentication Bypass via Host Header Spoofing

DeepSeek Harness before 0.1.2-alpha.1 contains an authentication bypass vulnerability that grants unauthenticated access to its local HTTP agent-control API by accepting a client-supplied loopback Host header in place of validating the actual TCP connection origin. On the default configuration, a...

NLTK: Corpus Reader Sandbox Bypass

Summary NLTK corpus-reader constructors can still reach outside-root file and database reads before the nltk.pathsec sandbox boundary is enforced. The PoC shows the safe path blocked by pathsec.open, then LinThesaurusCorpusReader and PanLexLiteCorpusReader succeeding in the same process. Affected...

NLTK: FileSystemPathPointer.open() sandbox check is dead code — arbitrary file read via file:// protocol

Summary There's a logic bug in FileSystemPathPointer.open inside nltk/data.py that makes the sandbox check permanently inert. The guard condition is always False — meaning any file the process can read is accessible by passing a file:// URL to nltk.data.load. --- Details In nltk/data.py,...

Although NLTK blocks absolute paths and .. traversal, the current boundary check is only lexical and does not account for symlink resolution. This lea...

Flounder turns modern coding agents into an end-to-end security audit system. Give it an authorized target boundary - a repository, source tree, package, deployed clue, or prior run - and the agent can prepare the workspace, read the code and supporting material, map the attack surface, dig into...
