zot create-only policy allows overwrite attempts of existing latest tag (update permission not required)

zot is ancontainer image/artifact registry based on the Open Container Initiative Distribution Specification. From 1.3.0 to 2.1.14, zot’s dist-spec authorization middleware infers the required action for PUT /v2/{name}/manifests/{reference} as create by default, and only switches to update when the tag already exists and reference != "latest". As a result, when latest already exists, a user who is allowed to create (but not allowed to update) can still pass the authorization check for an overwrite attempt of latest. This vulnerability is fixed in 2.1.15.

Craft Commerce has a SQL Injection in Commerce Purchasables Table Sorting

Craft Commerce is an ecommerce platform for Craft CMS. Prior to 4.10.2 and 5.5.3, Craft Commerce is vulnerable to SQL Injection in the purchasables table endpoint. The sort parameter is split by | and the first part (column name) is passed directly as an array key to orderBy() without whitelist validation. Yii2's query builder does NOT escape array keys, allowing an authenticated attacker to inject arbitrary SQL into the ORDER BY clause. This vulnerability is fixed in 4.10.2 and 5.5.3.

pypdf: manipulated stream length values can exhaust RAM

pypdf is a free and open-source pure-python PDF library. Prior to 6.8.0, an attacker who uses this vulnerability can craft a PDF which leads to large memory usage. This requires parsing a content stream with a rather large /Length value, regardless of the actual data length inside the stream. This vulnerability is fixed in 6.8.0.

SiYuan has a SVG Sanitizer Bypass via Whitespace in `javascript:` URI — Unauthenticated XSS

SiYuan is a personal knowledge management system. Prior to 3.5.10, SiYuan's SVG sanitizer (SanitizeSVG) checks href attributes for the javascript: prefix using strings.HasPrefix(). However, inserting ASCII tab (&#9;), newline (&#10;), or carriage return (&#13;) characters inside the javascript: string bypasses this prefix check. Browsers strip these characters per the WHATWG URL specification before parsing the URL scheme, so the JavaScript still executes. This allows an attacker to inject executable JavaScript into the unauthenticated /api/icon/getDynamicIcon endpoint, creating a reflected XSS. This is a second bypass of the fix for CVE-2026-29183 (fixed in v3.5.9). This vulnerability is fixed in 3.5.10.

Glances has SQL Injection via Process Names in TimescaleDB Export

Glances is an open-source system cross-platform monitoring tool. Prior to 4.5.1, The TimescaleDB export module constructs SQL queries using string concatenation with unsanitized system monitoring data. The normalize() method wraps string values in single quotes but does not escape embedded single quotes, making SQL injection trivial via attacker-controlled data such as process names, filesystem mount points, network interface names, or container names. This vulnerability is fixed in 4.5.1.

Envoy has an RBAC Header Validation Bypass via Multi-Value Header Concatenation

Envoy is a high-performance edge/middle/service proxy. Prior to 1.37.1, 1.36.5, 1.35.8, and 1.34.13, the Envoy RBAC (Role-Based Access Control) filter contains a logic vulnerability in how it validates HTTP headers when multiple values are present for the same header name. Instead of validating each header value individually, Envoy concatenates all values into a single comma-separated string. This behavior allows attackers to bypass RBAC policies—specifically "Deny" rules—by sending duplicate headers, effectively obscuring the malicious value from exact-match mechanisms. This vulnerability is fixed in 1.37.1, 1.36.5, 1.35.8, and 1.34.13.

Craft has a potential information disclosure vulnerability in preview tokens

Craft is a content management system (CMS). Prior to 4.17.4 and 5.9.7, Craft CMS has a CSRF issue in the preview token endpoint at /actions/preview/create-token. The endpoint accepts an attacker-supplied previewToken. Because the action does not require POST and does not enforce a CSRF token, an attacker can force a logged-in victim editor to mint a preview token chosen by the attacker. That token can then be used by the attacker (without authentication) to access previewed/unpublished content tied to the victim’s authorized preview scope. This vulnerability is fixed in 4.17.4 and 5.9.7.

Craft Commerce has a SQL Injection in Commerce Inventory Table Sorting

Craft Commerce is an ecommerce platform for Craft CMS. Prior to 5.5.3, Craft Commerce is vulnerable to SQL Injection in the inventory levels table data endpoint. The sort[0][direction] and sort[0][sortField] parameters are concatenated directly into an addOrderBy() clause without any validation or sanitization. An authenticated attacker with access to the Commerce Inventory section can inject arbitrary SQL queries, potentially leading to a full database compromise. This vulnerability is fixed in 5.5.3.

Envoy has an off-by-one write in JsonEscaper::escapeString()

Envoy is a high-performance edge/middle/service proxy. Prior to 1.37.1, 1.36.5, 1.35.8, and 1.34.13, an off-by-one write in Envoy::JsonEscaper::escapeString() can corrupt std::string null-termination, causing undefined behavior and potentially leading to crashes or out-of-bounds reads when the resulting string is later treated as a C-string.
