PYSEC-2026-2894 PPTAgent: Arbitrary File Write via `save_generated_slides`

Summary This vulnerability has been fixed in https://github.com/icip-cas/PPTAgent/commit/418491a9a1c02d9d93194b5973bb58df35cf9d00. The savegeneratedslides MCP tool accepts a pptxpath argument and writes the generated PPTX file to that path without any workspace restriction or path validation:...

PYSEC-2026-2521 InstructLab vulnerable to Path Traversal

A flaw was found in InstructLab. A local attacker could exploit a path traversal vulnerability in the chat session handler by manipulating the logsdir parameter. This allows the attacker to create new directories and write files to arbitrary locations on the system, potentially leading to...

PYSEC-2026-3393 UEFI Firmware Parser has a stack out-of-bounds write in tiano decompressor MakeTable

uefi-firmware contains a stack out-of-bounds write vulnerability in the native tiano/EFI decompressor. in uefifirmware/compression/Tiano/Decompress.c, MakeTable does not validate that bit-length values read from the compressed bitstream are within the expected range 0..16. a crafted firmware blob...

PYSEC-2026-2404 Bugsink affected by authenticated arbitrary file write in artifactbundle/assemble

Authenticated arbitrary file write in artifact bundle assembly Summary An authenticated file write vulnerability was identified in Bugsink 2.1.0 in the artifact bundle assembly flow. A user with a valid authentication token could cause the application to write attacker-controlled content to a...

PYSEC-2026-2845 OpenEXR has a signed 32-bit Overflow in PIZ Decoder Leads to OOB Read/Write

Summary internalexrundopiz advances the working wavelet pointer with signed 32-bit arithmetic: c wavbuf += nx ny wcount; Because nx, ny, and wcount are int, a crafted EXR file can make this product overflow and wrap. The next channel then decodes from an incorrect address. The wavelet decode path...

PYSEC-2026-2922 PraisonAI recipe registry publish path traversal allows out-of-root file write

Summary PraisonAI's recipe registry publish endpoint writes uploaded recipe bundles to a filesystem path derived from the bundle's internal manifest.json before it verifies that the manifest name and version match the HTTP route. A malicious publisher can place ../ traversal sequences in the bund...

PYSEC-2026-2848 OpenEXR: DWA Lossy Decoder Heap Out-of-Bounds Write

Summary The DWA lossy decoder constructs temporary per-component block pointers using signed 32-bit arithmetic. For a large enough width, the calculation overflows and later decoder stores operate on a wrapped pointer outside the allocated rowBlock backing store. This bug is reachable from the...

PYSEC-2026-2545 kedro-datasets has a path traversal vulnerability in PartitionedDataset that allows arbitrary file write

Impact PartitionedDataset in kedro-datasets was vulnerable to path traversal. Partition IDs were concatenated directly with the dataset base path without validation. An attacker or malicious input containing .. components in a partition ID could cause files to be written outside the configured...

PYSEC-2026-2899 PraisonAI Has Arbitrary File Write (Zip Slip) in Templates Extraction

The PraisonAI templates installation feature is vulnerable to a "Zip Slip" Arbitrary File Write attack. When downloading and extracting template archives from external sources e.g., GitHub, the application uses Python's zipfile.extractall without verifying if the files within the archive resolve...

PYSEC-2026-2989 pyLoad: Unprotected storage_folder enables arbitrary file write to Flask session store and code execution (Incomplete fix for CVE-2026-33509)

Summary The fix for CVE-2026-33509 GHSA-r7mc-x6x7-cqxx added an ADMINONLYOPTIONS set to block non-admin users from modifying security-critical config options. The storagefolder option is not in this set and passes the existing path restriction because the Flask session directory is outside both...

PYSEC-2026-2996 pyLoad SETTINGS Permission Users Can Achieve Remote Code Execution via Unrestricted Reconnect Script Configuration

Summary The setconfigvalue API endpoint allows users with the non-admin SETTINGS permission to modify any configuration option without restriction. The reconnect.script config option controls a file path that is passed directly to subprocess.run in the thread manager's reconnect logic. A SETTINGS...

PYSEC-2026-3001 PyMuPDF has a path traversal in _main_.py

A path traversal and arbitrary file write vulnerability exist in the embedded get function in 'main.py' in PyMuPDF version, 1.26.5...

PYSEC-2026-2656 Arbitrary file write via tar traversal in mlflow

A vulnerability in MLflow's pyfunc extraction process allows for arbitrary file writes due to improper handling of tar archive entries. Specifically, the use of tarfile.extractall without path validation enables crafted tar.gz files containing .. or absolute paths to escape the intended extractio...

PYSEC-2026-2398 BentoML Vulnerable to Arbitrary File Write via Symlink Path Traversal in Tar Extraction

Arbitrary File Write via Symlink Path Traversal in Tar Extraction Summary The safeextracttarfile function validates that each tar member's path is within the destination directory, but for symlink members it only validates the symlink's own path, not the symlink's target. An attacker can create a...

PYSEC-2026-2447 DiskCache has unsafe pickle deserialization

DiskCache python-diskcache through 5.6.3 uses Python pickle for serialization by default. An attacker with write access to the cache directory can achieve arbitrary code execution when a victim application reads from the cache...

USN-8533-1 openssh vulnerabilities

It was discovered that OpenSSH sftp did not properly constrain the location of downloaded files when connecting to an attacker-controlled server. An attacker could possibly use this issue to write files to unintended locations on the file system. CVE-2026-59995 It was discovered that OpenSSH scp...

CVE-2026-22102

A POST request sent to a specific webserver endpoint can be used to write to arbitrary file locations. The endpoint accepts the filename parameter in the Content-Disposition header without verification. This can be used to cause a denial of service by overwriting system files, or...
