Technical description

A flaw was found in MRTG. When the MRTG daemon is started as a root user and subsequently drops privileges, a local, low-privileged attacker can exploit a symbolic link (symlink) following vulnerability. By influencing or pre-placing a symlink in the process ID (PID) file path, the attacker can trick the root process into changing the ownership of an arbitrary existing file to the daemon user. This can lead to local privilege escalation, allowing unauthorized access to or modification of sensitive files.

———An NTLM coercion vulnerability exists on Windows nodes when the subPath supplied in a pod's volumeMounts is set to a symbolic link that points to an attacker-controlled network share. When a kubelet resolves symlinks, it does not reject a target that resolves to a UNC path. As a result, the kubelet will transparently attempt to authenticate to the share using NTLM. This allows an attacker to obtain the NetNTLMv2 hash of the account under which the kubelet is running. An attacker could then attempt to crack the hash to retrieve the corresponding password or relay it to impersonate the node, if the node is domain-joined.4h CVE-2026-1159087.4 HIG

———zip is a zip library for Rust that supports reading and writing simple ZIP files. From 7.2.0 until 9.0.0, ZipArchive::extract and ZipArchive::extract_unwrapped_root_dir use safe_prepare_path in src/read/zipfile.rs and simplified_components in src/path.rs to validate symbolic link targets with a lexical prefix comparison rather than resolving each intermediate link. An attacker who knows or can guess the absolute extraction destination can create a chain whose apparent target remains under the destination while an intermediate symlink resolves outside it, allowing attacker-controlled files to be created or overwritten with the extracting process's privileges. On Windows, discarded drive and UNC prefixes can permit a single-link escape when the process has SeCreateSymbolicLinkPrivilege, such as through administrator rights or Developer Mode. This regression is distinct from CVE-2025-29787. This issue is fixed in version 9.0.0.7h CVE-2026-1123446.8 MED

———Syncplify Server! before 8.8.0 contains a path traversal vulnerability that allows attackers with a symbolic link placed inside a user's home folder to access files outside the virtual filesystem root because confinement is enforced only against the requested path and not the on-disk destination of the link. Attackers can leverage a symlink or, on Windows, a directory junction that points outside the jail to read or access restricted files beyond the intended home-folder boundary.10h CVE-2026-1162134.9 MED

———Webasyst Framework through 4.4.0 contains an arbitrary file read vulnerability in waArchiveTar::writeItem() that creates symlinks from theme archives without validating link targets. Authenticated users with theme management rights can upload themes containing symlinks to wa-config/db.php or /etc/passwd and read them through the public theme path.10h CVE-2026-1155693.3 LOW

——2Fallow is a codebase intelligence tool for TypeScript and JavaScript. From 2.68.0 until 3.34.0, Fallow follows attacker-controlled Jest projects paths outside the project root through absolute paths, parent segments, dot-prefixed wildcard globs, or symlinks. In version 3.33.1, the same behavior also affects Vitest test.projects paths, Vitest inline-project extends paths, and symlinked script --config paths. Fallow parses the outside files as test-runner configuration and uses them to credit dependencies, setup files, and JSX import sources, which can change unused dependency and unused file findings in CI or agent analysis. The outside file contents are not printed or sent over the network. This issue is fixed in version 3.34.0.3d CVE-2026-11006310.0 CRI
