Open WebUI has a full SSRF Vulnerability in the RAG Web Search Feature

SSRF Bypass via IPv6/IPv4-mapped IPv6/IPv4-reserved-ranges in validateurl Summaryvalidateurl in backend/openwebui/retrieval/web/utils.py calls validators.ipv6ip, private=True, but the validators library does NOT implement the private keyword for IPv6 — the call raises a ValidationError which is...

Open WebUI: Read-Only Users Can Toggle Note Pin Status via Incorrect Permission Check (Write via Read-Only Access)

SummaryThe POST /api/v1/notes/id/pin endpoint performs a write operation toggling the ispinned field but only checks for read permission. Users with read-only access to a shared note can pin/unpin it, which is a state-modifying action that should require write permission. All other write endpoint...

pyzipper has an encryption bypass for small files encrypted using it

ImpactA Python operator precedence bug in pyzipper/zipfileaes.py caused the AE-2 format to never be automatically selected during encryption, regardless of file size or compression type. As a result, all encrypted entries are written in AE-1 format unless AE-2 is explicitly forced by the caller...

PraisonAI's symlink-extraction bypass of `_safe_extractall` writes outside `dest_dir`

SummaryThe safeextractall helper that all recipe pull, recipe publish, and recipe unpack flows route through validates each archive member's name for absolute paths, .. segments, and resolved-path escape — but does not validate member.linkname, does not reject symlink/hardlink members, and calls...

utcp-http vulnerable to SSRF via attacker-controlled OpenAPI servers[0].url in HTTP communication protocol

SummaryThe utcp-http plugin is vulnerable to a blind Server-Side Request Forgery SSRF caused by a trust-boundary inconsistency between manual discovery and tool invocation. registermanual validates the discovery URL against an HTTPS / loopback allowlist, but calltool and calltoolstreaming reuse t...

OpenStack Ironic has an Incorrect Resource Transfer Between Spheres

An issue was discovered in idrac in OpenStack Ironic before 35.0.1. During import, a user invoking molds can request authorization to be sent to a remote endpoint. The credential forwarded is a time-limited Keystone token which provides access to all OpenStack services Ironic is authorized for; o...

⚡ Weekly Recap: ShareFile Threat, Citrix Bleed 2 Ransomware, AI Coding Attacks, and More

Somewhere right now, a security tool is quietly finding bugs faster than any human can fix them. That's supposed to be the good news. The catch is that the attackers have the same tools, pointed the other way, and they don't file tickets. That's the shape of this week. Trusted code turns on the...

PYSEC-2026-3394 UEFI Firmware Parser has a heap out-of-bounds write in tiano decompressor ReadCLen

uefi-firmware contains a heap out-of-bounds write vulnerability in the native tiano/EFI decompressor. in uefifirmware/compression/Tiano/Decompress.c, ReadCLen reads Number = GetBitsSd, CBIT with CBIT = 9, so Number can be as large as 511, while the destination array Sd-mCLen has NC = 510 elements...

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-2026-2849 OpenEXR has heap-buffer-overflow via signed integer underflow in ImfContextInit.cpp

Summary A heap-buffer-overflow OOB read occurs in the istreamnonparallelread function in ImfContextInit.cpp when parsing a malformed EXR file through a memory-mapped IStream. A signed integer subtraction produces a negative value that is implicitly converted to sizet, resulting in a massive lengt...

JupyterLab vulnerable to potential authentication and CSRF tokens leak

ImpactUsers of JupyterLab who click on a malicious link may get their Authorization and XSRFToken tokens exposed to a third party when running an older jupyter-server version. PatchesJupyterLab 4.1.0b2, 4.0.11, and 3.6.7 were patched. WorkaroundsNo workaround has been identified, however users...
