7.5CVE-2026-82399: Resource Exhaustion Denial of Service in CoreDNS Custom Transports
CVE-2026-82399 is a resource management vulnerability in CoreDNS affecting custom DNS transport pathways. Prior to version 1.14.7, transports including DNS-over-HTTPS (DoH), DNS-over-QUIC (DoQ), and DNS-over-gRPC executed the resource-intensive unpack method of the underlying Go DNS library on raw, untrusted incoming payloads before validating the fixed 12-byte DNS header. An unauthenticated remote attacker can exploit this behavior by using nested DNS name compression pointers to trigger substantial heap allocations, leading to memory exhaustion and server termination.

7.5CVE-2026-84997: Infinite Loop Denial of Service in ReactPHP HTTP Component
An infinite loop vulnerability in ReactPHP's react/http chunked transfer encoding decoder (v0.6.0 up to 1.11.1) allows unauthenticated remote attackers to trigger a denial of service (DoS) by sending crafted chunked requests or responses, completely freezing the single-threaded event loop and pegging CPU usage to 100%.

6.1CVE-2026-88976: HTML Deserialization Cross-Site Scripting in @platejs/core
Plate core HTML deserialization APIs parse supplied HTML strings in the active document. When an application passes untrusted or cross-user HTML to these APIs, certain HTML attributes can trigger browser behavior before the HTML is converted into editor nodes.

5.3CVE-2026-85999: Regular Expression Denial of Service (ReDoS) in Soup Sieve css_parser.py
A polynomial-time Regular Expression Denial of Service (ReDoS) vulnerability in Soup Sieve versions prior to 2.9 allows remote unauthenticated attackers to cause CPU exhaustion and thread-pool denial of service. The vulnerability resides in the trailing whitespace and comment preprocessing step of the CSS parser. An attacker can trigger quadratic backtracking by submitting a crafted CSS selector string containing a long run of internal spaces or comments terminated by a non-matching token. This blocks the Python Global Interpreter Lock (GIL) and halts worker threads.

5.3CVE-2026-86000: Polynomial-Time Regular Expression Denial of Service in Soup Sieve Selector Parser
A regular expression denial of service (ReDoS) vulnerability in Soup Sieve prior to version 2.9 allows remote attackers to cause CPU exhaustion and service disruption. The issue lies within the definition of the IDENTIFIER and VALUE selector sub-patterns in the CSS parser component, which uses overlapping adjacent quantified groups. When parsing long, crafted, or unclosed CSS selectors, backtracking-based regular expression engines experience quadratic performance degradation. User-controlled selectors can reach this path through soupsieve.compile(), soupsieve.select(), or BeautifulSoup.select(), while applications using only hard-coded selectors are unaffected.

7.5CVE-2026-86003: Unintended Proxying of DNS UPDATE Requests via Alternative Transports in CoreDNS
A protocol-level validation bypass in CoreDNS versions prior to 1.14.7 allows unauthenticated remote attackers to proxy unauthorized DNS UPDATE messages (Opcode 5) using modern alternative transport layers such as DoH, DoH3, DoQ, and gRPC. If upstream authoritative servers trust the CoreDNS server's source IP and do not enforce TSIG authentication, attackers can inject, alter, or delete DNS zone records, leading to potential zone takeover or traffic redirection.

8.1CVE-2026-72695: Authenticated Path Traversal and Arbitrary File Deletion in Grav CMS MediaUploadTrait
A path traversal vulnerability exists in Grav CMS versions prior to 2.0.16. The flaw occurs within the file validation mechanisms of the MediaUploadTrait, enabling authenticated users with media management privileges to bypass sandbox limitations. This allows the deletion of arbitrary files on the filesystem, which can result in denial of service or remote code execution.

An unauthenticated directory traversal vulnerability exists in Grav CMS prior to version 2.0.15. Due to an insecure string-based containment check (str_starts_with) in the pre-boot static asset server, attackers can read files in sibling directories sharing a prefix with the configured asset path when plugin-asset-map.php is enabled.

CVE-2026-75828 is a critical stored cross-site scripting (XSS) vulnerability in the getgrav Grav CMS before version 2.0.15. The vulnerability resides in the detectXss() security filter mechanism, where parser-differential mismatches between the regular-expression-based server-side validation and browser HTML5 tokenization allow authenticated editors to bypass event-handler detection and inject arbitrary JavaScript execution vectors.

8.8CVE-2026-75827: Grav Arbitrary File Write & Remote Code Execution
An arbitrary file write and remote code execution vulnerability exists in Grav CMS before version 2.0.15. The vulnerability is caused by using an incomplete denylist validation approach for bare PHP functions in the Blueprint dynamic-data compiler, allowing authenticated users with page-editing or blueprint-configuration privileges to execute arbitrary functions such as error_log.

CVE-2026-75834 is a stored Cross-Site Scripting (XSS) vulnerability in Grav CMS core, caused by a design flaw in its input validation wrapper Security::detectXss(). Regular expressions using the PCRE UTF-8 /u modifier fail-open when encountering invalid UTF-8 sequences or when the PCRE JIT stack limit is exhausted, allowing authenticated users with page-editing privileges to save malicious HTML and scripts.
