Top Risky CVEs
| CVE | Summary | Severity | CVSS | EPSS | Priority | Signals |
|---|---|---|---|---|---|---|
| CVE-2026-4689 | A sandbox escape vulnerability exists in Firefox's XPCOM component due to incorrect boundary conditions and integer overflow, allowing attackers to bypass security sandboxing mechanisms. This affects Firefox versions below 149, Firefox ESR below 115.34, and Firefox ESR below 140.9. An attacker can exploit this flaw to escape the browser sandbox and potentially execute arbitrary code with elevated privileges on the affected system. | CRITICAL | 10.0 | 0.0% | 70 |
PoC
|
| CVE-2026-69253 | Authenticated remote code execution in FlowiseAI Flowise (versions ≤ 3.1.2, npm packages flowise and flowise-components) arises from a vm2 JavaScript sandbox escape reachable through the AgentAsTool, ChatflowTool, and ExecuteFlow nodes, which still run untrusted code in the deprecated in-process vm2 sandbox (useSandbox: false). An attacker who can edit a chatflow injects code via an unvalidated baseURL URL-hash fragment and abuses moment's CVE-2022-24785 path-traversal (whose fix is bypassable inside the sandbox) to break out of vm2 and run arbitrary commands as the Flowise service account, fully compromising the host. A complete working exploit is published in the elttam/GitHub advisory, but the flaw is not in CISA KEV. | CRITICAL | 9.0 | 0.3% | 65 |
PoC
|
| CVE-2026-70473 | Broken access control in Flowise's GET /api/v1/upsert-history API endpoint exposes the entire server-wide upsert history - exceeding 100MB per response - to any authenticated user, leaking sensitive infrastructure credentials including Qdrant server URLs, collection names, and vector pipeline configuration across all tenants and workspaces. The vulnerability is confirmed in flowise <= 3.1.2 and publicly documented in GHSA-fr6g-7cq8-fg82 with a working curl-based proof-of-concept, meaning any account holder on a multi-tenant deployment can harvest cross-tenant vector store configuration for reconnaissance or targeted follow-on attacks against exposed backends. Vendor-released patch flowise@3.1.3 is confirmed available and addresses missing workspace-scoping enforcement across multiple API controllers. | HIGH | 8.3 | 0.2% | 62 |
PoC
|
| CVE-2026-59931 | Server-side request forgery in PHPOffice PhpSpreadsheet (>= 4.0.0 through 5.8.0, plus older branches back to 2.0.0) lets an attacker bypass the WEBSERVICE() domain whitelist introduced in 5.4.0 by chaining through an HTTP 302/301 redirect. Because the whitelist only validates the initial URL host while file_get_contents() silently follows redirects without re-validation, an attacker who can upload a crafted XLSX to an app that calls setDomainWhiteList() and getCalculatedValue() can pivot to internal-only targets and read the full HTTP response (up to 32,767 bytes) as a cell value. Publicly available exploit code exists (a full PoC and lab reproduction are in the GitHub advisory); no public exploit identified as actively used in the wild and it is not in CISA KEV. | HIGH | 7.7 | 0.5% | 59 |
PoC
|
| CVE-2026-53553 | Path traversal in Goploy's `/deploy/fileDiff` endpoint (versions <=1.17.5) enables any authenticated low-privilege member to read arbitrary files on both the Goploy host and every SFTP-managed remote server registered in the system. The dual file read returns local content in the `srcText` response field and remote server content in `distText`, multiplying the blast radius across all managed deployment targets. Publicly available exploit code exists per the GitHub Security Advisory; this is not listed in CISA KEV, but exploitation conditions are trivially met under default Goploy configuration. | HIGH | 7.7 | 0.3% | 59 |
PoC
|
| CVE-2026-90648 | Sandbox escape in wasm2c (wabt ≤ 1.0.41) allows an attacker controlling WebAssembly content to achieve arbitrary read/write of host process memory and code execution by exploiting an unchecked calloc() return value during funcref table allocation. When calloc() fails, table->data is left NULL while table->size retains the guest-declared element count, causing bounds checks to pass and element accesses to resolve to absolute low-memory addresses - fully defeating the isolation wasm2c exists to provide. Firefox's RLBox sandboxing of Graphite, Hunspell, Ogg, Expat, and Woff2 libraries is affected, and a public proof-of-concept ('table flip') is available, though exploitation requires specific memory-failure conditions to be present. | HIGH | 7.1 | 0.1% | 56 |
PoC
No patch
|
| CVE-2026-55593 | Froxlor's standalone AJAX endpoint (lib/ajax.php) entirely bypasses the CSRF token enforcement present in lib/init.php, allowing a remote attacker to forge state-changing POST requests on behalf of any authenticated administrator who visits a malicious page. Successful exploitation modifies administrator API key properties - specifically injecting the attacker's IP into the allowed_from whitelist and setting valid_until to -1 (never expires) - creating a persistent foothold for future API abuse if the API secret is later obtained. A working proof-of-concept HTML page is included in the public GitHub security advisory (GHSA-xpr4-8vp6-c87j); no CISA KEV listing found at time of analysis. EPSS data was not provided, but the UI:R requirement and niche product footprint constrain real-world exploitation. | MEDIUM | 6.5 | 0.2% | 53 |
PoC
|
| CVE-2026-59941 | Uncontrolled resource consumption in dompdf's BMP image processing pipeline allows any unauthenticated attacker who can submit HTML to a dompdf-powered endpoint to exhaust server memory and stall PHP-FPM worker pools with a 169-byte HTTP request. The library trusts attacker-controlled BMP header dimensions without bounding width × height, causing PHP's GD extension to allocate a full native pixel canvas - bypassing PHP's memory_limit entirely because GD allocates through its own native allocator. A publicly available, verified proof-of-concept demonstrates ~12× memory amplification (34 MB control vs ~412 MB attack peak RSS) from identically-sized requests, making this a high-impact, low-effort denial-of-service primitive. No active exploitation confirmed in CISA KEV at time of analysis. | MEDIUM | 6.3 | 0.5% | 52 |

| CVE-2026-75874 | Sandbox escape in the Remote Settings Client component of Mozilla Firefox lets attacker-controlled code break out of the isolated content process and reach the more privileged parent process, and was resolved in Firefox 154. The flaw is classed as a protection-mechanism failure (CWE-693) and carries a maximal CVSS 3.1 base score of 10.0 with a changed scope, reflecting cross-boundary impact. There is no public exploit identified at time of analysis and the CVE is not listed in CISA KEV, so this is a high-severity but not yet actively-exploited issue. | CRITICAL | 10.0 | 0.4% | 50 |
|
| CVE-2026-16367 | Sandbox escape in Mozilla Firefox before version 153 stems from an invalid pointer (CWE-119 memory-safety error) in the Disability Access (accessibility) APIs component, letting an attacker who can execute code in a constrained content process break out of the browser sandbox and reach the more privileged parent process with full confidentiality, integrity, and availability impact (CVSS 10.0, scope-changed). No public exploit identified at time of analysis, and the EPSS probability is low (0.14%, 4th percentile), indicating no evidence of widespread exploitation despite the maximum CVSS score. | CRITICAL | 10.0 | 0.1% | 50 |
No patch
|
| CVE-2026-4688 | Sandbox escape in Mozilla Firefox's Disability Access APIs component due to a use-after-free memory vulnerability allows unauthenticated remote attackers to execute arbitrary code with full system compromise. Firefox versions below 149 and Firefox ESR below 140.9 are affected, with no patch currently available. The vulnerability is exploitable over the network without user interaction, presenting critical risk to all affected users. | CRITICAL | 10.0 | 0.0% | 50 |
|
| CVE-2026-4725 | Unauthenticated remote attackers can escape the Firefox sandbox through a use-after-free vulnerability in the Canvas2D graphics component, allowing arbitrary code execution on affected systems running Firefox versions prior to 149. The vulnerability requires no user interaction and impacts the entire system due to its critical severity and CVSS score of 10.0. No patch is currently available for this actively exploitable flaw. | CRITICAL | 10.0 | 0.0% | 50 |
|
| CVE-2026-4692 | A sandbox escape vulnerability exists in Firefox's Responsive Design Mode component that allows attackers to break out of the browser's security sandbox and access sensitive information. This affects Firefox versions prior to 149, Firefox ESR prior to 115.34, and Firefox ESR prior to 140.9. An attacker can exploit this vulnerability to disclose information by circumventing the sandbox restrictions that normally isolate web content from the browser's privileged context. | CRITICAL | 10.0 | 0.0% | 50 |
PoC
|
| CVE-2026-41512 | Remote code execution in ai-scanner versions 1.0.0 through 1.4.0 allows authenticated attackers to inject and execute arbitrary JavaScript code via the BrowserAutomation::PlaywrightService component. The vulnerability has a Critical CVSS score of 9.9 with scope change, enabling cross-boundary compromise of confidentiality, integrity, and availability. Vendor-released patch available in version 1.4.1 as of April 13, 2026, with GitHub Security Advisory GHSA-r27j-xxgx-f5vr confirming the fix. | CRITICAL | 9.9 | 0.2% | 50 |
|
| CVE-2026-74990 | Memory-corruption defects in Mozilla Firefox and its ESR channels allow potential arbitrary code execution when a user renders attacker-controlled web content, per Mozilla advisories MFSA2026-74 through MFSA2026-80. The flaws were found internally by Mozilla across Firefox 153 and ESR 115.38/140.13/153.0, and Mozilla states some showed evidence of memory corruption that could plausibly be exploited. No public exploit identified at time of analysis; the issues are already fixed in Firefox 154, ESR 115.39, 140.14, and 153.1. | CRITICAL | 9.8 | 0.6% | 50 |
