CWE-917
Improper Neutralization of Special Elements used in an Expression Language Statement
Monthly
Remote code execution in beetl 3.20.2 allows unauthenticated remote attackers to execute arbitrary code via the type.new function and property reflection. Public proof-of-concept exploit code exists, though EPSS exploitation probability is low (0.24%) and no active exploitation has been reported to CISA KEV.
Host-level remote code execution in n8n (n8n-io) occurs when an authenticated user with workflow create or modify permissions crafts a malicious expression that bypasses the sanitizer in the legacy expression evaluator's computed-member handler, executing arbitrary code as the n8n process. Because the legacy expression engine is the default in affected versions, standard deployments are exposed without any special configuration. No public exploit identified at time of analysis, though the flaw was reported by VulnCheck and carries a high CVSS 4.0 base score of 8.9.
Expression language injection in Soagen Informatics' Apinizer API management platform versions 2026.04.0 through 2026.04.5 allows remote unauthenticated attackers to inject malicious EL expressions that the server evaluates, resulting in arbitrary code execution. The flaw was reported by Turkey's national CERT (TR-CERT) and carries a CVSS 9.8 critical rating, though SSVC currently indicates no observed exploitation and no public exploit identified at time of analysis. A vendor patch is available in version 2026.04.6.
Expression Language Injection in Spring Web Flow exposes applications explicitly configured with WebFlowELExpressionParser to evaluation of malicious Unified EL expressions submitted by authenticated low-privilege users. Affected versions span the 2.5.x, 3.0.x, and 4.0.0 release lines; exploitation requires both non-default configuration and user interaction, which meaningfully constrains real-world risk despite the High confidentiality and integrity impact ratings. No public exploit code and no CISA KEV listing have been identified at time of analysis.
Server-Side Expression Language (SpEL) injection in Spring Data REST allows authenticated remote attackers to execute arbitrary expressions by sending JSON Patch requests targeting Map-typed entity properties. Affected versions span 3.7.0 through 5.0.5, and successful exploitation yields high confidentiality and integrity impact (CVSS 8.1). No public exploit identified at time of analysis, but the low attack complexity and network reachability make this a credible threat to any exposed REST repository accepting application/json-patch+json.
SpEL (Spring Expression Language) injection in Spring Data KeyValue and Spring Data Redis allows a network-accessible, low-privileged attacker to execute arbitrary SpEL expressions when applications pass unsanitized user-controlled Sort parameters directly to repository query methods delegating to SpelPropertyComparator. Affected versions span eight major release lines from 2.7.x through 4.0.x, making the exposure surface broad across Spring-based Java ecosystems. No public exploit identified at time of analysis and no CISA KEV listing, but the high confidentiality impact rating and network attack vector warrant prompt patching for any application that surfaces Sort query parameters to end users.
Remote code execution risk in Spring Data MongoDB arises from a SpEL expression injection flaw (CWE-917) triggered during parameter binding for repository methods annotated with @Query that use a capture-all placeholder. With CVSS 8.1 (AV:N/AC:H/PR:N/UI:N) and no public exploit identified at time of analysis, unauthenticated attackers who can influence query parameters reaching such a method could execute arbitrary SpEL expressions on the server.
Remote code execution in Eclipse GlassFish allows remote attackers to evaluate arbitrary Expression Language (EL) expressions through the gadget handler's server-side template rendering of .xml files, leading to full host compromise. The vulnerability (CVSS 9.6, CWE-917) requires user interaction but no authentication, and is demonstrable by submitting payloads like #{7*7} which the server evaluates to 49. No public exploit identified at time of analysis and the issue is not listed in CISA KEV.
Expression Language Injection in Apache OFBiz before 24.09.06 allows remote unauthenticated attackers to inject and evaluate EL expressions through unsanitized application inputs, yielding partial confidentiality and integrity impact on the affected system. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N) confirms exploitation is network-reachable with no authentication or user interaction, and SSVC classifies the attack as automatable - a meaningful signal given OFBiz's historical exposure to EL-class vulnerabilities. However, real-world urgency is moderated by a very low EPSS score (0.03%, 8th percentile), no public exploit code identified, and no active exploitation reported; vendor patch 24.09.06 is available.
Remote code execution in Offline Hospital Management System 5.3.0 stems from an insecure Electron renderer configuration where Node.js integration is enabled while context isolation is disabled, allowing JavaScript in the renderer to invoke Node.js APIs and run arbitrary OS commands. The flaw carries a CVSS 7.3 with network attack vector and no privileges required, though EPSS is low at 0.06% and no public exploit identified at time of analysis beyond a Medium write-up describing the technique.
