CVE Summary Severity CVSS EPSS Priority Signals
CVE-2026-23697 Remote code execution in Vtiger CRM before 8.4.0 lets an authenticated low-privileged user upload a malicious .phar file through the Documents module and execute arbitrary PHP. The extension denylist in config.inc.php omits .phar, and a stale Apache 2.2-syntax .htaccess is silently ignored on Apache 2.4, so the payload lands in a web-accessible directory reachable by unauthenticated HTTP - the attack begins authenticated but the final execution step is unauthenticated. Publicly available exploit code exists (published by VulnCheck/Jiva Security); no CISA KEV listing and no EPSS score were provided. HIGH 8.7 0.8% 64
PoC No patch
CVE-2026-23698 Authenticated remote code execution in Vtiger CRM through version 8.4.0 lets an administrator upload a crafted ZIP archive through the ModuleManager import feature and drop executable PHP files directly into the web-root modules/ directory, yielding a persistent web shell. Because Apache resolves and executes those PHP files before Vtiger's routing layer runs, the resulting shell bypasses the application's authentication entirely and survives independently of the attacker's login session. Publicly available exploit code exists (VulnCheck / Jiva Security), though there is no public exploit identified as being used in active attacks and it is not listed in CISA KEV. HIGH 8.6 0.9% 64
PoC No patch
CVE-2026-50229 Reflected XSS in Apache Tomcat's bundled 'number guess' example application exposes users of that demo page to script injection across all major Tomcat release lines from 7.0 through 11.0. The flaw resides in a sample JSP/servlet, not the core Tomcat runtime, meaning exploitation depends entirely on the example application being deployed and accessible - a configuration that violates standard production hardening guidance. No public exploit code or active exploitation has been identified at time of analysis; no CVSS vector was assigned by the reporter. MEDIUM 6.1 0.2% 51
PoC
CVE-2026-49257 Authentication bypass in StarTree mcp-pinot versions 3.0.1 and earlier exposes the Model Context Protocol HTTP server on 0.0.0.0:8080 by default with no authentication, allowing any network-adjacent attacker to invoke every MCP tool - including SQL execution, schema creation, and table-config mutation - against the backing Apache Pinot cluster using the server's own credentials. The maximum CVSS 10.0 score reflects a scope-changing confused-deputy condition. No public exploit identified at time of analysis, but the trivial reachability and presence of write/DDL tooling make exploitation straightforward once the port is found. CRITICAL 10.0 0.5% 50
CVE-2026-46752 Memory corruption in Apache Kvrocks' embedded Lua scripting engine allows a client able to run EVAL/EVALSHA commands to trigger a stack buffer overflow in the bit.tohex() function, potentially crashing the server or corrupting process memory toward code execution. Kvrocks is a Redis-protocol-compatible distributed key-value store, and this flaw was disclosed via the oss-security mailing list on 2026-06-25 alongside three other Kvrocks issues. There is no public exploit identified at time of analysis and the CVE is not listed in CISA KEV. CRITICAL 10.0 0.3% 50
No patch
CVE-2026-33264 Remote code execution in Apache Airflow before 3.3.0 lets a DAG author embed a malicious trigger whose attacker-controlled class path is loaded via an unrestricted import_string() when the Scheduler or API Server deserializes the serialized DAG, executing arbitrary code in those privileged processes and breaking the core Airflow boundary that DAG-author code must never run in the Scheduler/API Server. Reported by Apache with a fix in 3.3.0, it currently has no public exploit identified and a low EPSS of 0.69% (48th percentile), and it is not listed in CISA KEV. The practical severity depends heavily on how much a deployment trusts its DAG authors, since exploitation requires the ability to submit a DAG. CRITICAL 9.8 0.7% 50
CVE-2026-53913 Authentication bypass in Apache Camel's camel-keycloak component (versions 4.15.0-4.18.2 and 4.19.0-4.20.x) allows any caller presenting a non-null Authorization: Bearer header value - including an arbitrary string or a forged, unsigned JWT - to bypass Keycloak token verification entirely and access routes protected by KeycloakSecurityPolicy. The cryptographic token checks (signature, issuer, expiry) are embedded exclusively inside role and permission validation routines that are never invoked when requiredRoles and requiredPermissions are empty, which is the documented default 'Basic Setup.' Where the protected route connects to a code-execution-capable Camel producer, this authentication bypass can escalate to unauthenticated remote code execution; no public exploit has been identified at time of analysis. CRITICAL 9.8 0.3% 49
CVE-2026-40008 Unsafe reflection in Apache IoTDB's pipe processor lets a user-supplied fully qualified Java class name be loaded and instantiated via Class.forName().newInstance() with no allowlisting, enabling arbitrary class loading and likely remote code execution in the database server process. It affects all releases from 1.0.0 up to (but not including) 2.0.10 and is fixed in 2.0.10. No public exploit identified at time of analysis, and EPSS is low (0.25%, 17th percentile), though CISA SSVC rates the technical impact as total and considers exploitation automatable. CRITICAL 9.8 0.3% 49
CVE-2026-28564 Authentication bypass via capture-replay in Apache IoTDB (1.0.0 through 2.0.9) lets attackers reuse stale credentials against the REST interface because Basic Authentication continues to accept cached credentials that should have been invalidated. An attacker who has captured or previously held valid credentials can keep authenticating after those credentials should have expired or been revoked, gaining full read/write control of the time-series database. No public exploit identified at time of analysis, and EPSS is low (0.18%, 8th percentile), so no active exploitation is indicated despite the 9.8 CVSS. CRITICAL 9.8 0.2% 49
CVE-2026-24014 Arbitrary file write in Apache IoTDB DataNode (versions 1.3.3 up to but not including 2.0.8) allows attackers who can reach the internal DataNode RPC port to smuggle path-traversal sequences in an uploaded Trigger JAR filename, writing files outside the Trigger installation directory with the IoTDB process's privileges. Because the write is attacker-controlled, it can plausibly be escalated to remote code execution by overwriting configuration or startup artifacts. There is no public exploit identified at time of analysis, and the EPSS score is low (0.15%, 4th percentile), consistent with exploitation being gated on an exposed internal port rather than a default-reachable service. CRITICAL 9.8 0.1% 49
CVE-2026-62392 OS command injection in Apache Kylin (versions 4 through 5.0.3) allows attackers to execute arbitrary operating-system commands by supplying malicious job configuration parameters that a backend API passes unsanitized to the OS command line. Because Kylin runs as a distributed analytics engine, successful exploitation yields full host compromise with the privileges of the Kylin service account. Per the vendor CVSS (AV:N/PR:N), the flaw is scored as network-reachable and unauthenticated with high impact across confidentiality, integrity, and availability; no public exploit is identified at time of analysis, and it is not listed in CISA KEV. CRITICAL 9.8 1.8% 49
No patch
CVE-2026-62390 SQL injection in Apache Kylin (versions 4 through 5.0.3) allows attackers to inject arbitrary SQL through a backend API used to refresh the table catalog, where untrusted input is concatenated into a dynamically generated SQL statement. The upstream CVSS 3.1 vector rates this as unauthenticated (PR:N) with full confidentiality, integrity, and availability impact (9.8), enabling database read/write and potentially further compromise. There is no public exploit identified at time of analysis and it is not listed in CISA KEV. CRITICAL 9.8 0.7% 49
No patch
CVE-2026-41566 Privilege bypass in Apache Kvrocks exposes the internal APPLYBATCH command without proper permission enforcement, letting an authenticated low-privilege client write raw batches directly to the underlying RocksDB storage engine and bypass the server's command ACL model. The flaw (CWE-280, improper handling of permissions) carries a CVSS 4.0 base of 9.4 due to high integrity and availability impact and an irrecoverable-damage recovery rating. No public exploit identified at time of analysis, and it is not listed in CISA KEV; it was disclosed pre-NVD via the oss-security mailing list on 2026-06-25 alongside two sibling Kvrocks CVEs. CRITICAL 9.4 0.3% 47
No patch
CVE-2026-40005 Arbitrary file write in Apache IoTDB (versions 1.0.0 through 2.0.9) lets remote attackers plant files anywhere the IoTDB process can write by abusing an unsafe API that fails to sanitize user-supplied pathnames. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N) indicates unauthenticated network exploitation with high confidentiality and integrity impact, and controlled file placement can escalate to code execution or overwrite of critical files. No public exploit has been identified at time of analysis, and EPSS is low (0.16%, 5th percentile) despite the 9.1 severity. CRITICAL 9.1 0.2% 46
CVE-2026-58319 Missing authentication on Apache Doris Frontend (FE) HTTP REST administrative APIs allows any unauthenticated attacker with network reach to the FE HTTP service to invoke privileged administrative operations, degrading cluster integrity and availability up to full denial of service. All Apache Doris releases before 3.1.0 (per EUVD, the 2.1.0 through pre-3.1.0 line) are affected, and a fixed release exists in 3.1.0. There is no public exploit identified at time of analysis and the issue is not listed in CISA KEV; the 9.1 Critical CVSS reflects the trivial unauthenticated network exploitability rather than confirmed in-the-wild use. CRITICAL 9.1 0.3% 46
