The MCTP-over-I2C+GPIO target binding in Zephyr subsys/pmci/mctp/mctp i2c gpio target.c processes pseudo-register writes from an I2C bus master byte-by-byte in mctp i2c gpio target write received without validating the order or the receive buffer. In the affected versions the MCTP I2C GPIO RX MSG...

Important: acl security update

Access Control Lists ACLs are used to define fine-grained discretionary access rights for files and directories. The acl packages contain the getfacl and setfacl utilities needed for manipulating access control lists. Security Fixes: acl: Symlink traversal privilege escalation via libacl function...

Astro: composable `astro/hono` pipeline bypasses `security.checkOrigin` when `middleware()` is absent or misordered

Summary In the composable astro/hono pipeline, the security.checkOrigin protection is only installed by the middleware primitive. The actions and pages primitives each dispatch to user code independently, so a pipeline that mounts either primitive before or without middleware will bypass the orig...

Cross-site Request Forgery (CSRF)

Overview astro is an Astro is a modern site builder with web best practices, performance, and DX front-of-mind. Affected versions of this package are vulnerable to Cross-site Request Forgery CSRF via the security.checkOrigin logic when middleware is absent or mounted after actions or pages in the...

GHSA-R557-WFFQ-WVRC @astrojs/node: Backslash-prefixed paths not recognized as internal by trailing-slash redirect

Impact With trailingSlash: 'always' configured, the @astrojs/node standalone server's static file handler appends a trailing slash to request paths and issues a 301 redirect. Paths beginning with /\ slash-backslash were not recognized as internal paths, so the handler would echo the raw path back...

Permissive List of Allowed Inputs

Overview axios is a promise-based HTTP client for the browser and Node.js. Affected versions of this package are vulnerable to Permissive List of Allowed Inputs in the isLoopback and isIPv4Loopback functions of lib/helpers/shouldBypassProxy.js, which require the first IPv4 octet to be 127 and...

CVE-2026-57852

Affected product/Component: Grav CMS scheduler-webhook plugin. Vulnerability: Authentication bypass due to a short-circuit logic flaw in the webhook token validation, allowing unauthenticated remote attackers to trigger configured scheduled jobs. Impact (as described): An unauthenticated POST to ...

GHSA-8MPJ-M6QM-5QR8 Mistune directives/include: mutual `.. include::` recursion crashes the renderer with `RecursionError`, denial of service via two attacker-controlled markdown files

Summary Type: Uncontrolled recursion via mutual include. The Include directive checks for direct self-reference a.md cannot include a.md, but does not detect indirect cycles. Two markdown files that include each other a.md → includes b.md → includes a.md cause unbounded recursion until Python's...

Pillow GdImageFile.open: image dimensions accepted without decompressionbombcheck...

Pillow `GdImageFile._open()`: image dimensions accepted without `_decompression_bomb_check()`

Description PIL/GdImageFile.py GdImageFile.open reads image dimensions from the GD 2.x header and stores them in self.size without calling Image.decompressionbombcheck. Because GdImageFile is not registered with Image.registeropen, it never passes through the standard Image.open code path that...

Pillow `BdfFontFile`: `Image.new()` called without `_decompression_bomb_check()` — bomb protection bypass via font loading

Summary PIL/BdfFontFile.py bdfchar lines 84–88 reads the BBX width height field from a BDF font file and passes the dimensions directly to Image.new without calling Image.decompressionbombcheck. This completely bypasses Pillow's documented decompression bomb protection. Image.open enforces...

GHSA-5X94-69RX-G8H2 Pillow: `FontFile.compile()`: `Image.new()` called without `_decompression_bomb_check()`

Description PIL/FontFile.py FontFile.compile assembles per-glyph images into a single combined bitmap using Image.new"1", xsize, ysize without calling Image.decompressionbombcheck. This is the base-class method shared by both BdfFontFile and PcfFontFile, and it is triggered whenever a loaded font...

GHSA-5GJJ-6R7V-PH3X pillow-heif: Integer Overflow in Encode Path Buffer Validation Leads to Heap Out-of-Bounds Read

Summary An integer overflow in the encode path buffer validation of pillowheif.c allows an attacker to bypass bounds checks by providing large image dimensions, resulting in a heap out-of-bounds read. This can lead to information disclosure server heap memory leaking into encoded images or denial...
