Title
GFI Archiver MArc.Core Deserialization of Untrusted Data Remote Code Execution Vulnerability
Summary
GFI Archiver MArc.Core Deserialization of Untrusted Data Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GFI Archiver. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the configuration of the MArc.Core.Remoting.exe process, which listens on port 8017. The issue results from the lack of proper validation of user-supplied data, which can result in deserialization of untrusted data. An attacker can leverage this vulnerability to execute code in the context of SYSTEM. Was ZDI-CAN-27935.

Title
JS Archive List <= 6.1.7 - Authenticated (Contributor+) PHP Object Injection via 'included' Shortcode Attribute
Summary
The JS Archive List plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 6.1.7 via the 'included' shortcode attribute. This is due to the deserialization of untrusted input supplied via the 'included' parameter of the plugin's shortcode. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject a PHP Object. No known POP chain is present in the vulnerable software. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.

CVE-2026-1839 (GCVE-0-2026-1839)

Vulnerability from cvelistv5 – Published: 2026-04-07 05:22 – Updated: 2026-04-07 13:27

Title
Arbitrary Code Execution via Unsafe torch.load() in Trainer Checkpoint Loading in huggingface/transformers
Summary
A vulnerability in the HuggingFace Transformers library, specifically in the `Trainer` class, allows for arbitrary code execution. The `_load_rng_state()` method in `src/transformers/trainer.py` at line 3059 calls `torch.load()` without the `weights_only=True` parameter. This issue affects all versions of the library supporting `torch>=2.2` when used with PyTorch versions below 2.6, as the `safe_globals()` context manager provides no protection in these versions. An attacker can exploit this vulnerability by supplying a malicious checkpoint file, such as `rng_state.pth`, which can execute arbitrary code when loaded. The issue is resolved in version v5.0.0rc3.

CVE-2026-1462 (GCVE-0-2026-1462)

Vulnerability from cvelistv5 – Published: 2026-04-13 14:55 – Updated: 2026-07-15 01:21
VLAI
Title
Safe Mode Bypass in keras-team/keras
Summary
A vulnerability in the `TFSMLayer` class of the `keras` package, version 3.13.0, allows attacker-controlled TensorFlow SavedModels to be loaded during deserialization of `.keras` models, even when `safe_mode=True`. This bypasses the security guarantees of `safe_mode` and enables arbitrary attacker-controlled code execution during model inference under the victim's privileges. The issue arises due to the unconditional loading of external SavedModels, serialization of attacker-controlled file paths, and the lack of validation in the `from_config()` method.

CVE-2026-1426 (GCVE-0-2026-1426)

Vulnerability from cvelistv5 – Published: 2026-02-18 14:24 – Updated: 2026-04-08 16:43

Title
Advanced AJAX Product Filters <= 3.1.9.6 - Authenticated (Author+) PHP Object Injection via Live Composer Compatibility
Summary
The Advanced AJAX Product Filters plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 3.1.9.6 via deserialization of untrusted input in the shortcode_check function within the Live Composer compatibility layer. This makes it possible for authenticated attackers, with Author-level access and above, to inject a PHP Object. No known POP chain is present in the vulnerable software, which means this vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present via an additional plugin or theme installed on the target system, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code depending on the POP chain present. Note: This vulnerability requires the Live Composer plugin to also be installed and active.

CVE-2026-1360 (GCVE-0-2026-1360)

Vulnerability from cvelistv5 – Published: 2026-07-30 04:03 – Updated: 2026-07-30 14:03

Title
BuddyPress <= 14.5.0 - Authenticated (Subscriber+) PHP Object Injection via XProfile Field Data
Summary
The BuddyPress plugin for WordPress is vulnerable to Deserialization of Untrusted Data in all versions up to, and including, 14.5.0 This is due to the `bp_unserialize_profile_field()` function using `@unserialize()` without the `allowed_classes` parameter on user-controlled XProfile field data. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary PHP objects via XProfile textbox fields, which could lead to remote code execution if a suitable POP chain is available in the WordPress environment.

CVE-2026-1323 (GCVE-0-2026-1323)

Title
Insecure Deserialization in extension "Mailqueue" (mailqueue)
Summary
The extension fails to properly define allowed classes used when deserializing transport failure metadata. An attacker may exploit this to execute untrusted serialized code. Note that an active exploit requires write access to the directory configured at $GLOBALS['TYPO3_CONF_VARS']['MAIL']['transport_spool_filepath'].

Mitigation
Architecture and Design Implementation

If available, use the signing/sealing features of the programming language to assure that deserialized data has not been tainted. For example, a hash-based message authentication code (HMAC) could be used to ensure that data has not been modified.

Mitigation
Implementation

When deserializing data, populate a new object rather than just deserializing. The result is that the data flows through safe input validation and that the functions are safe.

Mitigation
Implementation

Explicitly define a final object() to prevent deserialization.

Mitigation
Architecture and Design Implementation
  • Make fields transient to protect them from deserialization.
  • An attempt to serialize and then deserialize a class containing transient fields will result in NULLs where the transient data should be. This is an excellent way to prevent time, environment-based, or sensitive variables from being carried over and used improperly.
Mitigation
Implementation

Avoid having unnecessary types or gadgets (a sequence of instances and method invocations that can self-execute during the deserialization process, often found in libraries) available that can be leveraged for malicious ends. This limits the potential for unintended or unauthorized types and gadgets to be leveraged by the attacker. Add only acceptable classes to an allowlist. Note: new gadgets are constantly being discovered, so this alone is not a sufficient mitigation.

Mitigation
Architecture and Design Implementation

Employ cryptography of the data or code for protection. However, it's important to note that it would still be client-side security. This is risky because if the client is compromised then the security implemented on the client (the cryptography) can be bypassed.

Mitigation MIT-29
Operation

Strategy: Firewall

Use an application firewall that can detect attacks against this weakness. It can be beneficial in cases in which the code cannot be fixed (because it is controlled by a third party), as an emergency prevention measure while more comprehensive software assurance measures are applied, or to provide defense in depth [REF-1481].

CAPEC-586: Object Injection

An adversary attempts to exploit an application by injecting additional, malicious content during its processing of serialized objects. Developers leverage serialization in order to convert data or state into a static, binary format for saving to disk or transferring over a network. These objects are then deserialized when needed to recover the data/state. By injecting a malformed object into a vulnerable application, an adversary can potentially compromise the application by manipulating the deserialization process. This can result in a number of unwanted outcomes, including remote code execution.
