| CVE-2026-86435 | 1 Thephpleague | 1 Commonmark | 2026-09-07 | 7.5 High |
| commonmark versions from 1.5.0 before 2.8.4 contain a denial of service vulnerability in the Footnote extension that fails to deduplicate footnote definitions. Attackers can craft documents with duplicate footnote definitions and references to create quadratic output expansion, consuming excessive memory and CPU to exhaust server resources. | ||||
| CVE-2026-86434 | 1 Thephpleague | 1 Commonmark | 2026-09-07 | 7.5 High |
| league/commonmark versions >= 2.0.0 and < 2.8.4 (patched in 2.9.0) contain a denial of service vulnerability in UniqueSlugNormalizer::normalize(), which restarts its numeric-suffix search from 1 on every slug collision, resulting in O(K^2) time complexity for K headings that collapse to the same base slug. The vulnerable path is reached when HeadingPermalinkExtension, FootnoteExtension, or TableOfContentsExtension is registered. An unauthenticated attacker can force many headings onto a single base slug (e.g., via empty ATX headings, identical heading text, or punctuation-only headings) in a small Markdown document, consuming excessive CPU and denying service. | ||||
| CVE-2026-86433 | 1 Thephpleague | 1 Commonmark | 2026-09-07 | 7.5 High |
| commonmark versions from 1.5.0 before 2.8.4 contain a denial of service vulnerability in the Attributes extension where AttributesListener::findTargetAndDirection() performs quadratic-time sibling list scanning. Unauthenticated attackers can submit approximately 32 KB of repeated attribute blocks to cause parsing to take over 5 seconds, exhausting server resources. | ||||
| CVE-2026-86432 | 1 Thephpleague | 1 Commonmark | 2026-09-07 | 5.3 Medium |
| commonmark versions from 2.0.0 before 2.8.4 contain a denial of service vulnerability in XmlRenderer that emits depth-proportional indentation for every XML tag. Attackers can provide deeply nested Markdown or AST structures to cause quadratic memory consumption and output amplification, exhausting server resources. | ||||
| CVE-2026-86431 | 1 Thephpleague | 1 Commonmark | 2026-09-07 | 7.2 High |
| league/commonmark (thephpleague/commonmark) versions >= 2.7.0 and < 2.9.1 contain a cross-site scripting vulnerability in the AttributesExtension. Prefixing an attribute name with a single U+000C form feed byte (e.g. {\x0Conclick="alert(1)"}) bypasses the AttributesHelper::filterAttributes() 'on*' event-handler filter because PHP's trim() does not strip U+000C, causing the attribute to be written verbatim into the output where browsers parse it as a genuine event handler. The same prefix also defeats the allow_unsafe_links check, allowing javascript: URIs through href/src attributes even when allow_unsafe_links is false. Exploitation requires processing untrusted Markdown with the AttributesExtension enabled; the injected script executes when the rendered HTML is viewed. Fixed in 2.9.1. | ||||
| CVE-2026-86430 | 1 Thephpleague | 1 Commonmark | 2026-09-07 | 7.5 High |
| league/commonmark versions before 2.9.1 contain multiple denial of service vulnerabilities in fenced code block detection, reference link label lookup, and emphasis delimiter processing that perform super-linear work on crafted input. Attackers can submit specially crafted Markdown with long backtick runs, nested brackets, or delimiter sequences to consume disproportionate CPU time and prevent legitimate requests from completing. | ||||
| CVE-2026-86429 | 1 Thephpleague | 1 Commonmark | 2026-09-07 | 7.5 High |
| The league/commonmark (thephpleague/commonmark) library in versions >= 1.5.0 and < 2.9.1 contains quadratic parsing complexity in its SmartPunctExtension and AttributesExtension. When either extension is explicitly registered on the Environment (they are not enabled by default and are excluded from the standard CommonMark and GitHub-Flavored Markdown converters), an unauthenticated attacker can submit small, specially crafted Markdown documents — such as text alternating with unpaired quotes, contiguous runs of block-level attribute blocks, or repeated class attributes — to trigger disproportionate CPU consumption and cause a denial of service. Fixed in 2.9.1. | ||||
| CVE-2026-86428 | 1 Thephpleague | 1 Commonmark | 2026-09-07 | 7.5 High |
| commonmark versions from 1.5.0 before 2.10.0 contain a denial of service vulnerability in the AttributesExtension when processing distinctly-named attributes. Attackers can submit Markdown with numerous distinct attribute names to cause quadratic-time attribute merging and filtering, consuming disproportionate CPU resources and preventing legitimate requests from completing. | ||||
| CVE-2026-86427 | 1 Librenms | 1 Librenms | 2026-09-07 | 8.8 High |
| LibreNMS before 26.8.0 contains an argument injection vulnerability in the graph_title parameter that allows authenticated attackers to inject arbitrary rrdtool arguments by breaking out of double-quote escaping. Attackers can inject DEF and LINE arguments to read RRD files from unauthorized devices, or use newline injection to execute arbitrary rrdtool commands, bypassing per-device authorization checks. | ||||
| CVE-2026-86426 | 1 Librenms | 1 Librenms | 2026-09-07 | N/A |
| LibreNMS before 26.8.0 contains an authentication bypass vulnerability in the REST API that allows unauthenticated attackers to access protected endpoints by sending numeric values instead of string tokens. Attackers can exploit MySQL type coercion by sending small integers like 0 through 9 to match token hashes, gaining access to API functionality including device credentials and administrative features that enable remote code execution through alert templates. | ||||
| CVE-2026-86425 | 1 Imagemagick | 1 Imagemagick | 2026-09-07 | 3.3 Low |
| ImageMagick before 7.1.2-30 and 6.9.x before 6.9.13-55 contains a heap-use-after-free vulnerability in the Layer method of PerlMagick. An attacker who supplies a crafted list of images can trigger memory access after deallocation, resulting in a crash (denial of service). | ||||
| CVE-2026-86424 | 1 Imagemagick | 1 Imagemagick | 2026-09-07 | 2.5 Low |
| ImageMagick before 7.1.2-30 and 6.9.13-55 contains a time-of-check-time-of-use (TOCTOU) vulnerability in the video decoder that allows attackers to bypass path policy write restrictions via symlink swaps. An attacker can replace a symlink between policy validation (check-time) and the file write operation (use-time) to write to policy-denied locations. | ||||
| CVE-2026-86423 | 1 Imagemagick | 1 Imagemagick | 2026-09-07 | 3.3 Low |
| ImageMagick before 7.1.2-30 and 6.9.x before 6.9.13-55 contains a heap-use-after-free vulnerability in the GetList method of PerlMagick. A crafted call to the GetList method can trigger the use-after-free, resulting in a crash (denial of service). | ||||
| CVE-2026-86422 | 1 Imagemagick | 1 Imagemagick | 2026-09-07 | 3.3 Low |
| ImageMagick before 7.1.2-30 contains a time-of-check-time-of-use vulnerability in path policy enforcement on Windows that allows attackers to bypass read or write restrictions by exploiting symlink race conditions. Attackers can swap symlinks between policy validation and file access to read or write policy-denied files. | ||||
| CVE-2026-86421 | 1 Imagemagick | 1 Imagemagick | 2026-09-07 | 3.7 Low |
| ImageMagick before 7.1.2-30 and 6.9.13-55 contains a memory leak in the MSL image decoder. A crafted MSL image triggers memory allocation without proper deallocation, allowing an attacker to exhaust memory and cause a denial of service. | ||||
| CVE-2026-86420 | 1 Imagemagick | 1 Imagemagick | 2026-09-07 | 3.7 Low |
| ImageMagick before 7.1.2-30 and 6.9.13-55 fails to properly lower the memory budget when an operation inside OpenPixelCache fails. Repeated triggering of such failures can exhaust the process memory budget and result in a denial of service. | ||||

| CVE-2026-12853 | 2026-09-07 | 5.4 Medium | ||
| The Flamingo plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 2.6.2. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with contributor-level access and above, to enumerate taxonomy terms including channel names derived from Contact Form 7 form titles that may reveal internal form purposes, department names, or workflow identifiers, as well as submission counts per channel and contact tag names. The plugin's flamingo_map_meta_cap() filter restricts access to Flamingo's admin UI but does not extend to WordPress core APIs such as XML-RPC wp.getTerms and admin-ajax ajax-tag-search. | ||||
| CVE-2026-86416 | 1 Ilias | 1 Ilias | 2026-09-07 | 5.4 Medium |
| ILIAS versions before 9.23, 10.11, and 11.4 contain an authorization bypass vulnerability in ilObjGroupGUI where saveMapSettingsObject() and updateGroupTypeObject() perform state-changing operations without write permission checks. Authenticated users with only read access to a group can craft POST requests to modify group map settings and didactic template assignments, changing group modes and permissions for all members. | ||||
