Date AddedLinkExcerpt
2026-11-06 NEW 2026RELATE LMS RCE via insecure Celery pickle deserialization news 2 min read Deser PythonAdvisory detailing RELATE LMS RCE via insecure Celery pickle deserialization. Exploitation occurs when Celery workers are configured to accept and deserialize untrusted pickle data, allowing an attacker to execute arbitrary commands. This vulnerability, combined with missing network isolation in code execution sandboxes, enables authenticated students to achieve full Remote Code Execution (RCE) on the host server by crafting a pickle payload and pushing it to the message broker.
2026-11-06 NEW 2026DocsGPT unauthenticated RCE via FAISS pickle deserialization news 2 min read AI Deser PythonAdvisory for GHSA-m448-vp23-j393 details an unauthenticated Remote Code Execution vulnerability in DocsGPT. Attackers can exploit this by uploading malicious FAISS index files (`index.pkl`) via the `/api/upload_index` endpoint. The application then uses `FAISS.load_local` with `allow_dangerous_deserialization=True`, enabling arbitrary command execution through `pickle` deserialization. This flaw bypasses authentication mechanisms like `AUTH_TYPE=simple_jwt` due to an application logic error in the `/api/upload_index` route.
2026-11-06 NEW 2026numcodecs Pickle codec arbitrary code execution on decode news 2 min read Deser PythonLibrary advisory detailing arbitrary code execution via the `numcodecs.pickles.Pickle` codec. When decoding untrusted data, the `pickle.loads` function can be invoked, allowing an attacker to inject malicious code. This vulnerability is triggered when reading array chunks whose metadata specifies the "pickle" codec, enabling remote code execution without direct user interaction.
2026-11-06 NEW 2026Xoscar unauthenticated cloudpickle RCE (CVE-2026-49950) news AI Deser PythonWriteup on CVE-2026-49950, an unauthenticated RCE vulnerability in Xorbits Xoscar up to v0.11.2. Attackers can exploit the `SocketChannel.recv()` method, which passes unvalidated data to `cloudpickle.loads()`. This allows for pickle reduce gadget execution before message type validation, enabling remote code execution as the server process, potentially with root privileges on GPU nodes.
2026-11-06 NEW 2026Mautic SSTI in theme templates (GHSA-9fx4-7cmj-47vg) intermediate SSTIWriteup of GHSA-9fx4-7cmj-47vg, a Server-Side Template Injection (SSTI) in Mautic theme templates. Unsandboxed Twig template rendering allows authenticated users with theme creation privileges to achieve Remote Code Execution by uploading malicious templates. Patched versions include 7.1.2, 6.0.9, 5.2.11, and 4.4.20 for ELTS. Restricting theme upload permissions is a mitigation.
2026-11-06 NEW 2026Remote Code Execution via Polyglot Web Shell Upload intermediate BurpThis vulnerability allows for Remote Code Execution (RCE) by uploading a "polyglot" file. Instead of disguising a PHP file as an image, this method creates a file that is genuinely both a valid image and a functional PHP script. This bypasses typical upload filters that would otherwise prevent such malicious uploads, enabling attackers to execute arbitrary code on the server.
2026-11-06 NEW 2026fsspec ReferenceFileSystem SSTI to RCE (CVE-2026-104851) intermediate 3 min read Python SSTIWriteup of CVE-2026-104851 in fsspec, an RCE vulnerability exploitable via Jinja2 Server-Side Template Injection. Attackers controlling a malicious Kerchunk JSON document, served via a URL, can achieve arbitrary Python code execution before any data is read. This mirrors CVE-2024-34359 in llama-cpp-python and affects fsspec versions from 0.9.0 onward. The vulnerability lies in the unsandboxed rendering of Jinja2 templates within the ReferenceFileSystem implementation.
2026-11-06 NEW 2026Trestle Jinja2 include SSTI incomplete fix (CVE-2026-57170) intermediate 4 min read Python SSTILibrary advisory for CVE-2026-57170 details an incomplete fix for Trestle's Jinja2 templating, allowing Server-Side Template Injection (SSTI) and leading to arbitrary code execution. The vulnerability stems from custom include tags that re-parse markdown content in a non-sandboxed Jinja2 environment, bypassing an earlier fix for CVE-2026-46439. This affects Trestle versions 4.0.3 and earlier, enabling attackers to inject malicious template code through untrusted OSCAL data.
2026-11-06 NEW 2026Stanza RCE via pickle deserialization in lemmatizer intermediate 2 min read AI Deser PythonLibrary for securing the Stanza NLP toolkit against arbitrary code execution. Versions 1.14.0 and later are vulnerable to Remote Code Execution (RCE) when loading attacker-supplied lemma checkpoints. This vulnerability arises because `torch.load` with `weights_only=True` does not inspect bytes values, allowing an unrestricted `pickle.loads` within `_unpack_pos_dict` to deserialize malicious payloads. A crafted checkpoint containing a `__reduce__` method can execute arbitrary commands upon model loading, as demonstrated by a Proof of Concept that created a file using `os.system`. The fix involves using the `RestrictedUnpickler` to deserialize the inner stream, preventing the execution of malicious code.
2026-11-06 NEW 2026Agenta Jinja2 evaluator SSTI allows RCE intermediate 1 min read AI Python SSTIWriteup of SSTI in Agenta's Jinja2 evaluator, allowing RCE (CWE-1336). Authenticated users can craft malicious Jinja2 templates, such as `{{ lipsum.__globals__['os'].popen('id').read() }}`, which are executed unsandboxed on the API server when template_format="jinja2" is used in AI critique evaluators or prompt templates. This vulnerability impacts self-hosted or managed Agenta platform deployments, granting arbitrary code execution and full filesystem access within the API server container.
2026-11-06 NEW 2026LMCache unauthenticated pickle RCE on multiprocess transport intermediate 3 min read AI Deser PythonWriteup detailing CVE-2026-105192, an unauthenticated pickle RCE vulnerability in LMCache's multiprocess ZeroMQ transport. The issue stems from unsafe deserialization of device IPC descriptors, allowing attackers to execute arbitrary code as the LMCache process user. This vulnerability impacts versions 0.3.9 through 0.5.5 and release candidates of 0.5.6, with official container images potentially running as root. The fix replaces pickle with validated MessagePack descriptors, and workarounds include restricting network access and binding the transport to localhost.
