CVE-2026-79939 Aug 26, 20:18 HIGH PATCH This Week

Symlink following in Dell PowerProtect Cyber Recovery (versions prior to 20.3.0.0) enables a low-privileged local attacker to perform script injection by redirecting privileged file operations through attacker-controlled symbolic links. All three impact dimensions - confidentiality, integrity, availability - are rated High by the vendor, reflecting the potential for full local system compromise on a sensitive data-protection appliance. No public exploit exists and EPSS sits at the 2nd percentile (0.11%), with SSVC confirming no observed active exploitation, indicating limited near-term real-world risk despite the High CVSS score.

CVE-2026-75038 Aug 25, 10:00 MEDIUM PATCH This Month

Symlink following in LACT (Linux AMDGPU Control Tool) versions through 0.10.0 allows a local low-privileged user to redirect privileged file operations to attacker-chosen paths via a crafted UNIX symbolic link, resulting in local denial-of-service. Reported by SUSE and tracked in their Bugzilla (bsc#1276481), the flaw is rooted in CWE-61 and is confined to systems with multi-user local access where LACT is installed. No public exploit code has been identified and the issue does not appear in the CISA KEV catalog.

CVE-2026-64846 Aug 20, 16:18 LOW PATCH Monitor

Sandbox escape in Nix versions before 2.35.0 allows a malicious build derivation - executed under the experimental `recursive-nix` feature - to create or truncate empty files outside the build sandbox using the nix-daemon's permissions by exploiting a TOCTOU race in the LocalStore path-restore logic. The race window exists between path resolution and the `open()` call with `O_TRUNC` in `writeFile`, which previously lacked `O_NOFOLLOW` enforcement, letting an attacker substitute a symlink mid-flight to redirect the write. No public exploit has been identified and the vulnerability is not listed in CISA KEV; the official fix is confirmed in Nix 2.35.0.

CVE-2026-32657 Aug 18, 18:17 HIGH PATCH This Week

Symlink following vulnerability across nine Dell enterprise storage and infrastructure products enables a locally authenticated, low-privileged attacker to elevate their privileges, potentially achieving full system compromise (C:H/I:H/A:H). Affected platforms span Dell AppSync 4.6.0.0, Metro Node 8.0.0, UCC Edge 3.0.1, VxRail 8.0.322, PowerMax 10.3.0, Unity 5.4, PowerFlex Manager 4.5.4, PowerFlex Intelligent Catalog 46.377.00 and 46.382.00, and PowerFlex Rack 4.5.4 and prior. No public exploit code has been identified and this CVE is not listed in the CISA KEV catalog at time of analysis, but the breadth of affected Dell enterprise products and the high-impact CVSS metrics make patching a priority for organizations running Dell storage infrastructure.

CVE-2026-53802 Aug 13, 14:32 HIGH This Week

Arbitrary file read in rsync before 3.5.0 enables attackers with local low-privilege access to read files accessible to the rsync daemon process by exploiting improper symlink resolution in input configuration file handling. The vulnerability affects --files-from, --password-file, and filter merge file paths, allowing placement of a symlink at a predictable argument path or supply of a --files-from path that escapes the daemon module root. No public exploit code or active exploitation (CISA KEV) has been identified at time of analysis; the vendor has released a confirmed fix in rsync 3.5.0.

CVE-2026-54574 Jul 29, 16:32 PyPI HIGH POC PATCH GHSA This Week

Arbitrary host file write in termux/proot-distro before 5.1.5 lets a malicious rootfs tarball or Docker layer plant an absolute-path symlink during `proot-distro install`, so a follow-up file member is written through that symlink onto the host filesystem - outside the container, before it is ever run. The install/reset paths (_extract_plain_tar) and the Docker layer path (_apply_layer) validated member names for '..' traversal but never validated symlink targets in member.linkname. No public exploit identified at time of analysis and it is not in CISA KEV, but the flaw is confirmed and fully described by the vendor GHSA advisory with vulnerable source shown.

Arbitrary code execution in Cribl Stream before 4.18.2 allows a remote authenticated attacker with Pack import and pipeline preview permissions to compromise the server. The attacker can execute arbitrary code as the Cribl server process by importing a crafted Git repository containing a symbolic link in the pack's functions directory. No public exploit is known, and there is no evidence of active exploitation at this time.

Symlink following in HuggingFace Datasets through version 5.00 allows local low-privileged attackers to redirect archive extraction to arbitrary filesystem locations by pre-planting symlinks at predictable output paths in the shared cache directory. When a higher-privileged user or automated service subsequently triggers Extractor.extract(), the library writes archive contents through the attacker-controlled symlink, enabling overwrite of sensitive system files and potential privilege escalation or code execution. A publicly available exploit exists and an upstream fix is available via commit ad2d853, though no confirmed tagged release version has been independently verified.

CVE-2026-12080 Jul 20, 12:40 HIGH This Week

Local privilege escalation to root in the QEMU Guest Agent (qga) affects Red Hat Enterprise Linux 6 through 10, RHEL for NVIDIA 26, and OpenShift Container Platform 4, where a local unprivileged guest user abuses the guest-ssh-add-authorized-keys command handler through symlink manipulation to seize ownership of arbitrary root-owned files. Two attack variants exist - a deterministic directory-symlink bypass and a TOCTOU file-symlink race - both requiring an external management layer such as libvirt to invoke the code path. No public exploit is identified at time of analysis and it is not listed in CISA KEV, but the CVSS 7.3 rating and clean path to full root access make it a meaningful local escalation risk in multi-tenant virtualization estates.
