HighCVSS 7.5Exploitation Probability (EPSS)
Elevated risk56th percentile - higher than 56% of all known CVEs
Summary
An issue was discovered in zola versions 0.13.0 through 0.17.2 related to the web server implementation. The handle_request function does not account for sequences of special path control characters in the URL, allowing directory traversal and reading arbitrary files from the filesystem.
Risk Assessment
This vulnerability may lead to the exposure of sensitive data from the filesystem, posing a significant security risk to the organization.
Recommendation
It is recommended to update zola to the latest version to mitigate this vulnerability and to monitor server logs for potential exploitation attempts.

- CVE-2026-96659Critical
A flaw in Foreman allows an authenticated user with low-level Viewer permissions to cause unauthorized information disclosure by submitting requests to template preview endpoints. The user can access sensitive data such as host root passwords. Under insecure configurations with Safemode disabled, the flaw may also allow arbitrary command execution as the Foreman system account.
- CVE-2026-96658Critical
A flaw in Foreman allows an authenticated attacker with low-level permissions to achieve remote code execution (RCE) by bypassing the Safemode sandbox within the templating engine. Due to improper handling of delegated methods, the attacker can append unauthorized functions to the allowed execution list, enabling arbitrary command execution on the hosting server.
- CVE-2026-13043Critical
The Kernel Memory Access Driver (PSKMAD) used by WatchGuard endpoint security products does not properly enforce authentication. A local, authenticated attacker can bypass the driver's access-control handshake and issue arbitrary privileged commands to the driver, resulting in disclosure of kernel and process memory.
- CVE-2026-94620Critical
Classroom 50 prior to version 1.11.0, when running `gh teacher download`, clones each student's assignment repository and then writes autograde artifacts (`result.json` and `results.json`) into the just-cloned working tree. The write followed symlinks, so a student who committed `result.json` or `results.json` as a symlink could redirect the teacher's write to an arbitrary path (e.g. `~/.zshrc`, `~/.ssh/authorized_keys`, a cron file, or an in-clone `.git/hooks/*` file), with attacker-controlled bytes. This is an arbitrary file write leading to code execution as the teacher, whose `gh` token carries `admin:org`, `repo`, and `workflow` across the entire classroom organization.

Fortra's Core Privileged Access Manager (BoKS) contains a stack-based buffer overflow vulnerability in boks_autoregisterd. A remote attacker with network access to the autoregistration service may be able to trigger memory corruption during client response processing.
- CVE-2026-79898Critical
Fortra BoKS Manager contains a command injection vulnerability in crlserver. An authenticated user authorized to add CRL URLs through BCC, the WSI REST or SOAP API, or the cacrl command-line interface could cause shell command substitution to be processed by crlserver as root on the BoKS Master.

In deployments using BoKS keytab management, affected versions of boks_keytabmd generate Active Directory service-account passwords from a predictable pseudo-random sequence seeded with the current Unix timestamp. An attacker who knows the service principal and can estimate the password-change time can reproduce a limited candidate set and verify candidates offline.
- CVE-2026-103264Critical
Fleet versions before 4.87.0 contain an authentication bypass vulnerability in the device API that accepts hostnames and hardware serials as authentication tokens in addition to device UUIDs. Unauthenticated attackers who know or guess these non-secret identifiers can authenticate as iOS/iPadOS hosts to read device data and trigger device-scoped actions including software installation and MDM migration.
Original NVD description (English source)
An issue was discovered in zola 0.13.0 through 0.17.2. The custom implementation of a web server, available via the "zola serve" command, allows directory traversal. The handle_request function, used by the server to process HTTP requests, does not account for sequences of special path control characters (../) in the URL when serving a file, which allows one to escape the webroot of the server and read arbitrary files from the filesystem.
