CVE-2026-41264 Apr 21, 20:19 CRITICAL POC PATCH GHSA Act Now

Remote code execution in FlowiseAI Flowise (<= 3.0.13) allows attackers to run arbitrary OS commands on the server hosting a chatflow that uses the CSV Agent node. The CSV_Agents.run method evaluates LLM-generated Python in a non-sandboxed pyodide environment, and its FORBIDDEN_PATTERNS regex allow-list can be bypassed to import the os module and invoke system commands. An unauthenticated attacker can reach this via prompt injection against the chatflow, or an authenticated attacker can point the node at an attacker-controlled model server; publicly available exploit code exists, though EPSS remains low at 0.11%.

OS command injection in NewSoft NewSoftOA allows remote unauthenticated attackers to execute arbitrary system commands on the server.

Based on CVSS vector, this is remotely exploitable without authentication. No CISA KEV listing or public exploit code identified at time of analysis, but network accessibility and lack of auth barriers make this a high-priority remediation target for organizations running NewSoftOA.

CVE-2026-39386 Apr 21, 00:50 HIGH PATCH GHSA This Week

Privilege escalation in Neko virtual browser (versions 3.0.0-3.0.10, 3.1.0-3.1.1) allows any authenticated user with low privileges to immediately gain full administrative control over the entire instance, including member management, room settings, broadcast control, and session termination. This complete instance compromise requires only network access and valid user credentials (CVSS 8.8, AV:N/AC:L/PR:L). While EPSS exploitation probability is low (0.12%, 31st percentile) and no active exploitation has been confirmed, the vulnerability is trivially exploitable by any authenticated user and classified as non-automatable but with total technical impact per SSVC. Vendor patches are available in versions 3.0.11 and 3.1.2.

CVE-2026-3298 Apr 21, 14:45 HIGH PATCH This Week

Out-of-bounds buffer write in CPython's asyncio.ProactorEventLoop (Windows only) allows remote attackers to trigger memory corruption via oversized network data. The sock_recvfrom_into() method lacks buffer size validation when the nbytes parameter is used, enabling writes beyond allocated memory boundaries. Patch available via GitHub PR #148809. CVSS 8.8 reflects network-accessible attack surface with no authentication required, though exploitation is platform-specific (Windows only) and requires specific asyncio usage patterns.

Privilege escalation in Firefox WebRender allows remote attackers to gain elevated access through malicious web content requiring user interaction. Affects Firefox versions before 150, Firefox ESR before 115.35, and Firefox ESR before 140.10. Mozilla released patches in advisories MFSA2026-30 through MFSA2026-34. CVSS 8.8 (High) severity with network attack vector, but exploitation requires user interaction (visiting malicious site). No public exploit identified at time of analysis, with SSVC framework indicating no confirmed exploitation and partial technical impact.

CVE-2026-40496 Apr 21, 01:38 HIGH PATCH This Week

Insecure token generation in FreeScout <1.8.213 allows unauthenticated remote attackers to download private email attachments by forging MD5-based download tokens. The predictable formula (md5(APP_KEY + sequential_attachment_id + guessable_size)) enables enumeration of all stored attachments without credentials. CVSS 8.8 reflects high confidentiality and integrity impact via network vector with no authentication required. EPSS data not provided. Proof-of-concept exploitation exists (E:P in CVSS vector). Vendor-released patch version 1.8.213 available via GitHub.

CVE-2026-31018 Apr 21, 00:00 HIGH GHSA This Week

Authenticated users with restricted HTML/JavaScript editing permissions in Dolibarr ERP & CRM 22.0.4 and earlier can escalate privileges to execute arbitrary PHP code via the Website module. The vulnerability exploits inconsistent permission enforcement across input parameters during website page creation, allowing low-privileged authenticated users to bypass intended restrictions and inject PHP code. Public proof-of-concept exists on GitHub (PhDg1410), though no active exploitation is confirmed by CISA KEV. EPSS data unavailable, but the CVSS 8.8 score reflects high impact across confidentiality, integrity, and availability when exploited by authenticated insiders or compromised accounts.

State corruption in UltraDAG 0.1 allows remote unauthenticated attackers to bypass authorization controls and manipulate blockchain state integrity through malformed SmartOp::Vote transactions. The vulnerability enables attackers to trigger state mutations before authorization checks complete, causing high availability impact and low integrity impact to the blockchain. No active exploitation or public POC has been identified, but the CVSS vector (AV:N/AC:L/PR:N/UI:N) indicates trivial remote exploitation against default configurations. Upstream fixes are available via GitHub commits but no tagged release version has been confirmed.

Privilege escalation in Firefox's Debugger component allows remote attackers to gain elevated system privileges after user interaction with a malicious site. Affects Firefox versions prior to 150 and Firefox ESR versions prior to 140.10. CVSS 8.8 severity with network attack vector and no authentication required. SSVC framework indicates no active exploitation detected and non-automatable attack pattern. Vendor-released patches available in Firefox 150 and Firefox ESR 140.10 per Mozilla security advisories MFSA2026-30 through MFSA2026-34.

Remote attackers can escalate privileges in Firefox and Firefox ESR through a flaw in the Networking component when a user interacts with malicious content. The vulnerability affects Firefox versions prior to 150 and Firefox ESR versions prior to 140.10, allowing attackers with no initial privileges to achieve high impact on confidentiality, integrity, and availability. Mozilla has released patches for both product lines. EPSS data not available; no confirmed active exploitation (not listed in CISA KEV); public exploit code status unknown.

CVE-2026-40906 Apr 21, 20:05 HIGH PATCH This Week

Authenticated SQL injection in ElectricSQL's Electric Postgres sync engine (1.1.12 up to before 1.5.0) lets any authenticated user of the /v1/shape API smuggle arbitrary SQL through the order_by parameter. Because the shape layer forwarded the user-supplied ORDER BY string into a query with only permissive validation, crafted ORDER BY expressions (subqueries, casts, function calls) achieve error-based injection with full read, write, and destroy access to the backing PostgreSQL database. No public exploit identified at time of analysis and EPSS is very low (0.03%), but the fix (1.5.0) and PR diff are public.

Remote filesystem bridge in OpenClaw (<2026.3.31) enables sandbox escape through a TOCTOU race condition in readFile validation. Authenticated remote attackers can exploit the timing gap between path validation and file read operations to bypass sandbox restrictions and access arbitrary files outside the intended security boundary, potentially compromising both confidentiality and integrity of the underlying system. EPSS score of 0.03% (7th percentile) suggests low probability of widespread exploitation despite CVSS 8.8 severity, though patch availability from vendor (commit 121870a) enables defenders to remediate proactively before active exploitation begins.
