BACnet Stack is a BACnet open source protocol stack C library for embedded systems. Prior to versions 1.4.4 and 1.5.1, a remote attacker can trigger an uncontrolled recursion and stack overflow in the default server application of bacnet-stack by abusing the Channel object. This issue has been patched in versions 1.4.4 and 1.5.1.

CVE-2026-1263565.3 MED—
———Hono is a Web application framework that provides support for any JavaScript runtime. From 4.5.1 until 4.13.16, validator('form') uses a strict whole-header pattern that fails to recognize multipart/form-data when its Content-Type includes another legal parameter or extra whitespace after a semicolon. The validation callback receives an empty object even though c.req.parseBody() or c.req.formData() can still parse and expose all submitted fields to the handler. An unauthenticated client can therefore bypass allow-list or required-field checks when the application relies on the form validator and its callback accepts an empty object. application/x-www-form-urlencoded requests are not affected. This issue is fixed in version 4.13.16.2hCVE-2026-1263484.3 MED—
———Addressable is an alternative implementation to the URI implementation that is part of Ruby's standard library. From 2.0.0 until 2.9.1, the pure-Ruby Addressable::IDNA.to_unicode implementation decodes invalid Punycode A-labels instead of returning them unchanged. Labels that decode to ASCII text or fail to convert back to the same A-label can therefore make Addressable::URI#display_uri show a trusted-looking host while host, normalized_host, and the connection target retain the attacker-controlled encoded host. A trusted-name comparison using Addressable::IDNA.to_unicode output can also treat two different hosts as the same without displaying the URI. The native libidn implementation, to_ascii, and normalized_host are unaffected. This issue is fixed in version 2.9.1.4hCVE-2026-1262055.3 MED—
———Loofah is a general library for manipulating and transforming HTML/XML documents and fragments, built on top of Nokogiri. Prior to 2.25.3, the Loofah HTML5 sanitizer checks href and xlink:href on elements in SVG_ALLOW_LOCAL_HREF with a regular expression whose line anchor and newline-matching whitespace cause an all-whitespace value to be rescanned from every line start. An attacker can submit an SVG reference element with a long multiline-whitespace attribute and consume CPU quadratically during sanitization. CRuby 3.1 and earlier and JRuby are affected, while CRuby 3.2 and later uses linear-time regular-expression matching. The default safelist reaches the vulnerable check without a configuration change. This issue is fixed in version 2.25.3.4hCVE-2026-472588.2 ALT—
———BACnet Stack is a BACnet open source protocol stack C library for embedded systems. Prior to versions 1.4.4, 1.5.1, and 1.6.0, a stack-based out-of-bounds write exists in the Notification Class object implementation when handling AddListElement for the recipient-list property. This issue has been patched in versions 1.4.4, 1.5.1, and 1.6.0.4hCVE-2026-472578.1 ALT—
———BACnet Stack is a BACnet open source protocol stack C library for embedded systems. In versions 1.5.0 and 1.6.0-rc1, there is a restore logic flaw in bacnet-stack that is reachable through the official, unmodified apps/server management path when BACNET_BACKUP_RESTORE is enabled. This issue has been patched in versions 1.5.1 and 1.6.0.4hCVE-2024-21954——
———Improper exception handling in IOMMU could allow an invalidate command to be sent to PCIe devices that do not support Address Translation Cache (ATC), potentially resulting in denial of service.7h
