No public exploit code or active exploitation has been confirmed at time of analysis.

Arbitrary user metadata modification in Users Manager - PN plugin for WordPress (versions ≤1.1.15) allows unaneticated remote attackers to escalate privileges and hijack accounts. The vulnerability stems from flawed authorization logic in userspn_ajax_nopriv_server() that fails to verify authentication when user_id is supplied, combined with publicly exposed nonce values. Attackers can modify critical user metadata including userspn_secret_token for any WordPress user. CVSS 9.8 (Critical). EPSS data not available. No public exploit identified at time of analysis, but exploitation requires only HTTP requests with predictable parameters.

On Linux, if the target of Root.Chmod is replaced with a symlink while the chmod operation is in progress, Chmod can operate on the target of the symlink, even when the target lies outside the root. The Linux fchmodat syscall silently ignores the AT_SYMLINK_NOFOLLOW flag, which Root.Chmod uses to avoid symlink traversal. Root.Chmod checks its target before acting and returns an error if the target is a symlink lying outside the root, so the impact is limited to cases where the target is replaced with a symlink between the check and operation.

An attacker with local access and user-level privileges can exploit improper permission settings on critical directories to achieve full system compromise, requiring user interaction (file execution or folder navigation). This vulnerability has a CVSS score of 6.7 reflecting high confidentiality, integrity, and availability impact despite the elevated barriers to exploitation.

Local privilege escalation in Acronis True Image (Windows) before build 42902 allows authenticated users with low privileges to gain high-integrity access through DLL hijacking. An attacker with local user access can exploit unsafe DLL loading to execute arbitrary code with elevated permissions, requiring user interaction (e.g., triggering a specific application action). No public exploit code or active exploitation has been confirmed at the time of analysis.

Local privilege escalation in Acronis True Image for Windows before build 42902 exploits DLL hijacking to allow authenticated users to escalate privileges. An attacker with local access and valid credentials can manipulate DLL load paths during application execution, requiring user interaction (such as opening a file or launching a feature), to gain elevated system privileges. This vulnerability has a CVSS score of 6.7 and affects all versions prior to the patched build.

Unauthenticated privilege escalation in SignalK Server (versions prior to 2.24.0-beta.4) allows remote attackers to inject administrator roles via the /enableSecurity endpoint, granting full administrative control without credentials. Attackers can modify vessel routing data, alter server configurations, and access all restricted endpoints. No public exploit identified at time of analysis, but the critical CVSS 9.4 score reflects the trivial exploit complexity (AV:N/AC:L/PR:N) and high confidentiality/integrity impact to marine vessel control systems.

Authorization code forgery in Red Hat Keycloak enables unauthenticated attackers to escalate privileges to admin-level access tokens. The SingleUseObjectProvider's lack of type and namespace isolation permits attackers to forge valid authorization codes remotely, though exploitation requires high complexity (AC:H). No public exploit identified at time of analysis, with CVSS 7.4 indicating high confidentiality and integrity impact but no availability disruption.

Unblinded BPF immediate values in PROBE_MEM32 stores bypass constant hardening in the Linux kernel BPF JIT compiler when bpf_jit_harden >= 1, allowing user-controlled 32-bit immediates to leak into native code. The vulnerability affects Linux kernel versions where convert_ctx_accesses() rewrites arena pointer stores to BPF_ST|BPF_PROBE_MEM32 before constant blinding runs, but bpf_jit_blind_insn() only handles BPF_ST|BPF_MEM instructions. No public exploit code or active exploitation has been identified; the issue is a hardening bypass that could facilitate information disclosure or facilitate construction of more complex attacks against BPF programs.

Local privilege escalation in HCL BigFix Platform on Windows allows authenticated users with low privileges to access cryptographic private keys due to overly permissive file system permissions, potentially enabling complete system compromise with cross-scope impact. Authentication required (PR:L). No public exploit identified at time of analysis, though the attack is rated low complexity and fully automated. CVSS 8.8 severity driven by scope change and complete confidentiality/integrity/availability impact.

Percona PMM before version 3.7 allows authenticated remote code execution through improper privilege management in its internal database user. An attacker with pmm-admin credentials can leverage the 'Add data source' feature to escape database isolation and execute arbitrary shell commands on the underlying operating system, requiring only valid pmm-admin access rather than direct system-level privileges.

Stored XSS via HTML entity-encoded javascript: URLs in SVG files in phpMyFAQ enables privilege escalation from editor to admin. The regex-based sanitizer in SvgSanitizer.php fails to detect entity-encoded payloads like &#106;&#97;&#118;&#97;&#115;&#99;&#114;&#105;&#112;&#116;&#58; (javascript:), allowing any user with edit_faq permission to upload malicious SVGs that execute arbitrary JavaScript in admin browsers. Publicly available proof-of-concept demonstrates both basic XSS and complete admin account creation, with confirmed working exploitation in Chrome 146 and Edge.

Path traversal in Ferret's IO::FS::WRITE and IO::FS::READ functions enables remote code execution when web scraping operators process attacker-controlled filenames. The vulnerability affects github.com/MontFerret/ferret (all v2.x and earlier versions), allowing malicious websites to write arbitrary files outside intended directories by injecting '../' sequences into filenames returned via scraped content. Attackers can achieve RCE by writing to /etc/cron.d/, ~/.ssh/authorized_keys, shell profiles, or web server directories. Vendor-released patch available via commit 160ebad6bd50f153453e120f6d909f5b83322917. CVSS 8.1 (High) reflects network attack vector with low complexity requiring user interaction. No public exploit identified at time of analysis beyond the proof-of-concept in the GitHub advisory, and not listed in CISA KEV.

Stored cross-site scripting in CI4MS backend user management allows authenticated attackers with low-level privileges to inject malicious JavaScript that executes automatically when administrators access affected pages, enabling session hijacking and full administrative account takeover. The vulnerability affects all versions prior to 0.31.0.0 with a critical CVSS score of 9.9 due to scope change and high impact across confidentiality, integrity, and availability. EPSS data not available; no public exploit code or active exploitation confirmed at time of analysis, though the technical barrier is low (AC:L, PR:L).

Local privilege escalation in Himmelblau versions 2.0.0-alpha through 2.3.8 and 3.0.0-alpha through 3.1.0 allows authenticated users to assume privileged group membership when their Azure Entra ID-mapped CN or short name collides with system group names (sudo, wheel, docker, adm, etc.). The NSS module resolves the collision to the attacker's fake primary group, potentially granting group-level privileges if the system uses NSS for authorization decisions. CVSS 6.3 (medium); no public exploit identified at time of analysis.

Local privilege escalation to SYSTEM via race condition in Lakeside SysTrack Agent 11 (versions prior to 11.2.1.28) allows unauthenticated local attackers to gain complete system control through timing-dependent exploitation. EPSS risk assessment and KEV status not available at time of analysis; no public exploit identified at time of analysis. Attack complexity is rated high, requiring precise timing manipulation of concurrent operations.

DLL search path hijacking in Foxit PDF Editor and Foxit PDF Reader update services enables local privilege escalation to SYSTEM. Low-privileged authenticated users can plant malicious libraries in writable directories that are resolved during update checks, achieving arbitrary code execution with elevated privileges. CVSS 7.8 (High) with low attack complexity. No public exploit identified at time of analysis, EPSS data not provided.

Installer privilege escalation in Foxit PDF Reader and Foxit PDF Editor allows local authenticated users to execute arbitrary code with elevated system privileges via DLL search path manipulation. The installer's failure to use absolute paths for system executables enables attackers to plant malicious DLLs in user-writable directories that take precedence during installation, exploiting the trusted installer's elevated permissions. EPSS data not available; no public exploit identified at time of analysis; not listed in CISA KEV.

File Browser's self-registration mechanism grants arbitrary shell command execution to unauthenticated attackers when administrators enable signup alongside server-side execution. The signupHandler inherits Execute permissions and Commands lists from default user templates but only strips Admin privileges, allowing newly registered users to immediately execute arbitrary commands via WebSocket with the process's full privileges. Vendor patch available. EPSS data not provided, but the specific configuration requirement (signup + enableExec + Execute in defaults) significantly narrows the attack surface despite the network-accessible, unauthenticated attack vector (CVSS 8.1 High). No confirmed active exploitation (CISA KEV) or public exploit code identified at time of analysis beyond the detailed proof-of-concept in the advisory.

Stored XSS in File Browser's EPUB preview function (versions ≤v2.62.1) allows authenticated attackers to steal JWT tokens and escalate privileges by uploading malicious EPUB files. The vulnerability arises from passing allowScriptedContent:true to the epub.js library combined with an ineffective iframe sandbox (allow-scripts + allow-same-origin), enabling JavaScript in crafted EPUBs to access parent frame localStorage. CVSS 7.6 (AV:N/AC:L/PR:L/UI:R/S:C). No public exploit identified at time of analysis beyond the detailed PoC in the advisory. EPSS data not available. Vendor-released patch available per GitHub advisory. Low-privilege users with file upload permissions can weaponize this to compromise administrator sessions.
