Vulnerability from github – Published: 2026-06-19 20:46 – Updated: 2026-06-19 20:46

Summary

Python Liquid: Infinite loop when parsing malformed `{% case %}` tags

Details

Impact

Given a malformed {% case %} tag without associated {% when %} or {% else %} block, and no terminating {% endcase %} tag, Python Liquid hangs in an infinite loop at parse time. This allows malicious template authors to craft templates for a denial of service attack.

Patches

The issue is fixed in version 2.2.1 with the correction of the liquid.TokenStream.eof attribute. The kind and value of the special EOF token are now the same, so either can be tested against liquid.token.TOKEN_EOF.

Workarounds

Manually correct the definition of liquid.TokenStream.eof before parsing any templates.

import liquid
from liquid.token import TOKEN_EOF

liquid.stream.TokenStream.eof = liquid.Token(TOKEN_EOF, TOKEN_EOF, -1, "")

Vulnerability from github – Published: 2026-04-22 21:25 – Updated: 2026-04-22 21:25

Summary

justhtml has sanitization bypass in custom policies and programmatic DOM

Details

Summary

justhtml 1.17.0 fixes multiple security issues in sanitization, serialization, and programmatic DOM handling.

Most of these issues affected advanced or custom configurations rather than the default safe path.

Affected versions

justhtml <= 1.16.0

Fixed version

justhtml 1.17.0 released on April 19, 2026

Impact

Custom SVG / MathML sanitization policies

Custom policies that preserved foreign namespaces could allow dangerous content to survive sanitization, including:

active HTML integration points such as SVG <foreignObject>, MathML <annotation-xml encoding="text/html">, SVG <title> / <desc>, and MathML text integration points
mutation-XSS parser-differential payloads that looked inert in memory but became active HTML after reparse
SVG filter="url(...)" attributes that could trigger external fetches

These issues affected: - JustHTML(..., sanitize=True) with custom foreign-namespace policies - sanitize() / sanitize_dom() - low-level terminal Sanitize(...) transform execution

Preserved `<style>` handling

Constructor-time sanitization and explicit Sanitize(...) transforms did not fully match sanitize() / sanitize_dom() when custom policies preserved <style>.

That could leave resource-loading CSS such as @import or background-image:url(...) in sanitized output from HTML string input.

Programmatic DOM serialization

Programmatic script, style, and Comment(...) nodes could still serialize into active markup in some edge cases.

This could affect applications that build or mutate DOM trees directly before calling to_html() or to_markdown(html_passthrough=True).

Cache mutation and DOM cycle handling

Two lower-severity hardening fixes were included:

compiled sanitize-pipeline caches could be mutated after warming and weaken later sanitization
parent/child cycles in programmatic DOM trees could cause infinite loops in operations such as to_html() and sanitize_dom()

Default configuration

Most of the issues above did not affect ordinary parsed HTML with the default JustHTML(..., sanitize=True) configuration.

The main risk areas were:

custom policies that preserve SVG or MathML
custom policies that preserve <style>
programmatic DOM construction or mutation
low-level direct sanitizer/transform APIs

Recommended action

Upgrade to justhtml 1.17.0.

If users cannot upgrade immediately:

avoid preserving SVG or MathML for untrusted input
avoid preserving <style> for untrusted input
avoid mutating programmatic DOM trees with untrusted script, style, or comment content
avoid mutating warmed policy internals or sanitizer caches

Credit

Discovered during an internal security review of justhtml.

Severity

6.0 (Medium)

GHSA-VRX2-VJH6-FHXX

Vulnerability from github – Published: 2023-08-23 21:30 – Updated: 2024-01-13 00:30

Details

A vulnerability in the Simple Network Management Protocol (SNMP) service of Cisco FXOS Software for Firepower 4100 Series and Firepower 9300 Security Appliances and of Cisco UCS 6300 Series Fabric Interconnects could allow an authenticated, remote attacker to cause a denial of service (DoS) condition on an affected device.

This vulnerability is due to the improper handling of specific SNMP requests. An attacker could exploit this vulnerability by sending a crafted SNMP request to an affected device. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a DoS condition.

Note: This vulnerability affects all supported SNMP versions. To exploit this vulnerability through SNMPv2c or earlier, an attacker must know the SNMP community string that is configured on an affected device. To exploit this vulnerability through SNMPv3, the attacker must have valid credentials for an SNMP user who is configured on the affected device.

Severity

7.7 (High)

GHSA-VVC7-QVMV-VPJW

Vulnerability from github – Published: 2024-05-20 12:30 – Updated: 2025-01-16 18:30

Details

In the Linux kernel, the following vulnerability has been resolved:

virtio_net: Do not send RSS key if it is not supported

There is a bug when setting the RSS options in virtio_net that can break the whole machine, getting the kernel into an infinite loop.

Running the following command in any QEMU virtual machine with virtionet will reproduce this problem:

# ethtool -X eth0  hfunc toeplitz

This is how the problem happens:

1) ethtool_set_rxfh() calls virtnet_set_rxfh()

2) virtnet_set_rxfh() calls virtnet_commit_rss_command()

3) virtnet_commit_rss_command() populates 4 entries for the rss scatter-gather

4) Since the command above does not have a key, then the last scatter-gatter entry will be zeroed, since rss_key_size == 0. sg_buf_size = vi->rss_key_size;

5) This buffer is passed to qemu, but qemu is not happy with a buffer with zero length, and do the following in virtqueue_map_desc() (QEMU function):

if (!sz) { virtio_error(vdev, "virtio: zero sized buffers are not allowed");

6) virtio_error() (also QEMU function) set the device as broken

vdev->broken = true;

7) Qemu bails out, and do not repond this crazy kernel.

8) The kernel is waiting for the response to come back (function virtnet_send_command())

9) The kernel is waiting doing the following :

  while (!virtqueue_get_buf(vi->cvq, &tmp) &&
     !virtqueue_is_broken(vi->cvq))
      cpu_relax();

10) None of the following functions above is true, thus, the kernel loops here forever. Keeping in mind that virtqueue_is_broken() does not look at the qemu vdev->broken, so, it never realizes that the vitio is broken at QEMU side.

Fix it by not sending RSS commands if the feature is not available in the device.

Severity

5.5 (Medium)

  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nvirtio_net: Do not send RSS key if it is not supported\n\nThere is a bug when setting the RSS options in virtio_net that can break\nthe whole machine, getting the kernel into an infinite loop.\n\nRunning the following command in any QEMU virtual machine with virtionet\nwill reproduce this problem:\n\n    # ethtool -X eth0  hfunc toeplitz\n\nThis is how the problem happens:\n\n1) ethtool_set_rxfh() calls virtnet_set_rxfh()\n\n2) virtnet_set_rxfh() calls virtnet_commit_rss_command()\n\n3) virtnet_commit_rss_command() populates 4 entries for the rss\nscatter-gather\n\n4) Since the command above does not have a key, then the last\nscatter-gatter entry will be zeroed, since rss_key_size == 0.\nsg_buf_size = vi-\u003erss_key_size;\n\n5) This buffer is passed to qemu, but qemu is not happy with a buffer\nwith zero length, and do the following in virtqueue_map_desc() (QEMU\nfunction):\n\n  if (!sz) {\n      virtio_error(vdev, \"virtio: zero sized buffers are not allowed\");\n\n6) virtio_error() (also QEMU function) set the device as broken\n\n    vdev-\u003ebroken = true;\n\n7) Qemu bails out, and do not repond this crazy kernel.\n\n8) The kernel is waiting for the response to come back (function\nvirtnet_send_command())\n\n9) The kernel is waiting doing the following :\n\n      while (!virtqueue_get_buf(vi-\u003ecvq, \u0026tmp) \u0026\u0026\n\t     !virtqueue_is_broken(vi-\u003ecvq))\n\t      cpu_relax();\n\n10) None of the following functions above is true, thus, the kernel\nloops here forever. Keeping in mind that virtqueue_is_broken() does\nnot look at the qemu `vdev-\u003ebroken`, so, it never realizes that the\nvitio is broken at QEMU side.\n\nFix it by not sending RSS commands if the feature is not available in\nthe device.",

GHSA-VW2J-3XRW-2Q58

Vulnerability from github – Published: 2022-05-24 17:30 – Updated: 2022-05-24 17:30

Details

In Wireshark through 3.2.7, the Facebook Zero Protocol (aka FBZERO) dissector could enter an infinite loop. This was addressed in epan/dissectors/packet-fbzero.c by correcting the implementation of offset advancement.
