CVE-2026-128100

Vault vulnerable to ACL deny bypass via case-variant auth method user and group names

Vault Community Edition and Vault Enterprise did not apply explicit ACL policy deny rules to letter case variants of user and group names in auth methods that treat these names as case-insensitive. This may allow an authenticated user with delegated permissions to modify a protected user or group, potentially leading to privilege escalation. This vulnerability (CVE-2026-128100) is fixed in Vault Community Edition 2.2.2 and Vault Enterprise 2.2.2, 1.21.14, and 1.19.25.

CVE-2026-62973

BACnet Stack: Remote Global-Buffer-Overflow Read in readpropm via Malformed ReadPropertyMultiple-ACK

BACnet Stack is a BACnet open source protocol stack C library for embedded systems. Prior to versions 1.4.5, 1.5.1, and 1.6.0, a remote out-of-bounds read exists in the official BACnet client application apps/readpropm in bacnet-stack commit e2bdbf6. When readpropm sends a legitimate ReadPropertyMultiple request to a malicious BACnet/IP peer, the peer can reply with a malformed but structurally valid ReadPropertyMultiple-ACK that drives the client into a global-buffer-overflow read on the global receive buffer Rx_Buf. This issue has been patched in versions 1.4.5, 1.5.1, and 1.6.0.

BACnet Stack: AtomicReadFile/AtomicWriteFile stream fileStartPosition validation flaw causes out-of-bounds read/write in RAM file backends

BACnet Stack is a BACnet open source protocol stack C library for embedded systems. From versions 1.4.2 to before 1.4.5, and 1.5.0 to before 1.5.1, a signed fileStartPosition taken from AtomicReadFile and AtomicWriteFile stream-access requests is not validated tightly enough before it reaches the RAM file backends. Practical impact includes: reliable denial of service via process crash, out-of-bounds read that may expose adjacent memory contents, or out-of-bounds write that may corrupt heap memory and destabilize the process. This issue has been patched in versions 1.4.5 and 1.5.1.

CVE-2026-126063

Nokogiri: Mutation XSS through `noscript` content in Nokogiri's HTML5 serializer

Nokogiri is an open source XML and HTML library for the Ruby programming language. From 1.12.0 until 1.19.5, the C extension on CRuby and TruffleRuby has a Nokogiri::HTML5 serializer that does not escape text inside noscript elements or angle brackets inside attribute values. When an application sanitizes untrusted HTML with the default parsing options, allows noscript, and sends serialized output to a scripting-enabled browser, the browser can parse markup that Nokogiri did not produce, enabling mutation cross-site scripting. Using parse_noscript_content_as_text: true is the recommended workaround, not the vulnerable default. JRuby is not affected because it does not implement Nokogiri::HTML5. This issue is fixed in version 1.19.5.

gittuf: Policy rules bypassed in the presence of global rules

In gittuf 0.10.0 through 0.15.0, when a minimum threshold global rule and a policy rule protect the same namespace, verification gives the global rule's check over all trusted users in the policy precedence over the policy rule's own authorized users. A user listed in the policy file but not authorized by the policy rule, or fewer users than the rule's threshold, can make changes to the protected namespace that pass verification.

Mongoid stores encrypted fields in plaintext when two models share a collection

A flaw in the automatic client-side encryption schema generation of the Mongoid ODM may cause values that an application declared for encryption to be written and stored as cleartext when more than one model is mapped onto the same storage location. No error or warning is raised. A party holding an ordinary read-only database account, with no access to the encryption key material, may then obtain those values in clear form.

BACnet Stack is a BACnet open source protocol stack C library for embedded systems. Prior to versions 1.4.5, 1.5.1, and 1.6.0, the bsc_node_parse_urls() function in src/bacnet/datalink/bsc/bsc-node.c contains three distinct bugs when parsing space-separated WebSocket URIs from a BACnet/SC Address Resolution ACK message. Two bugs cause out-of-bounds writes past the utf8_urls[10][129] array in the static BSC_ADDRESS_RESOLUTION structure. This issue has been patched in versions 1.4.5, 1.5.1, and 1.6.0.

BACnet Stack: Out-of-bounds read in BACnet/SC proprietary header-option decode (bvlc_sc_decode_proprietary_option)

BACnet Stack is a BACnet open source protocol stack C library for embedded systems. Prior to versions 1.4.5, 1.5.1, and 1.6.0, a BACnet/SC peer can trigger a heap out-of-bounds read (up to 3 bytes), pre-authentication, in the BACnet/SC header-option decoder. bvlc_sc_decode_proprietary_option() reads the vendor-id and option-type at fixed offsets [3],[4],[5] before checking the option's declared header length, and the option-list validator never enforces a minimum length for proprietary options. This issue has been patched in versions 1.4.5, 1.5.1, and 1.6.0.

BACnet Stack: Out-of-bounds read in lighting_command_decode (full APDU size passed to nested tag decoders)

BACnet Stack is a BACnet open source protocol stack C library for embedded systems. Prior to versions 1.4.5, 1.5.1, and 1.6.0, lighting_command_decode in src/bacnet/lighting.c decodes its first field with the bounded apdu_size - apdu_len, but every nested decode in the operation switch is called with the original full apdu_size while the read pointer has been advanced to &apdu[apdu_len]. The leaf decoders bound their reads against the size they are told, so they read up to apdu_len bytes past the end of the caller's buffer, resulting in an out-of-bounds read. This issue has been patched in versions 1.4.5, 1.5.1, and 1.6.0.

Post to Google My Business plugin for WordPress before 3.5.7 contains a blind server-side request forgery vulnerability that allows authenticated users with Contributor-level privileges or higher to make the server send requests to arbitrary hosts by supplying an unvalidated mbp_post_attachment URL that reaches a raw getimagesize() call in validate_external_image_size() via the preview REST route. Attackers can exploit this to perform internal port scanning, probe internal-only services and cloud metadata endpoints, and trigger GET-based side effects on internal systems, bypassing network perimeter controls since the request originates from the web server.
