Vulnerabilities

Tesseract OCR 5.5.3 and earlier fails to validate counts read from the legacy INTTEMP component of .traineddata files: Classify::ReadIntTemplates uses NumClassPruners, NumClasses, and NumProtoSets as loop bounds without capping them against their maximums, and writes heap pointers past the fixed-capacity ClassPruners and ProtoSets arrays. An attacker who can supply or replace a .traineddata file consumed by Tesseract triggers this during legacy-classifier initialization, before any OCR output, gaining heap corruption, a crash (denial of service), or potentially controlled corruption. All deployments running Tesseract 5.5.3 or earlier are affected, particularly applications, document pipelines, and services that load traineddata files from untrusted or user-controlled sources. No fixed release is available as of this review, and no public proof-of-concept, KEV listing, or known in-the-wild exploitation exists.

Do: No patched version is available yet, so mitigate by ensuring Tesseract only loads .traineddata files from trusted sources and treat user-supplied traineddata as untrusted input. Deployments using only LSTM-based recognition can check whether their pipelines load legacy INTTEMP components, since the flaw is reached during legacy-classifier initialization. Monitor the tesseract-ocr GitHub repository for a fixed release and upgrade promptly once published.

Improper Neutralization of Input During Web Page Generation ("Cross-site Scripting") vulnerability in Drupal Address Suggestion allows Cross-Site Scripting (XSS). This issue affects Address Suggestion versions: from 0.0.0 to 1.0.25.

multer 2.2.0 leaks a file descriptor each time a multipart upload using diskStorage is aborted or truncated before completion, because the destination write stream is never closed. An unauthenticated network client can trigger this simply by repeatedly starting uploads and interrupting them. Each failed request leaves an open file descriptor and retains its disk blocks until the process exits, so sustained repeated failures can exhaust the process's file descriptor limit and cause a full denial of service (availability impact only). Any Node.js application running multer 2.2.0 with disk storage enabled is affected. There is no known public proof-of-concept, the flaw is not in CISA KEV, and EPSS puts 30-day exploitation probability at 0.3%, so no confirmed exploitation is known; a fixed release (2.3.0) is available and no workarounds are provided.

Do: Upgrade multer to 2.3.0 or later, which closes the write stream on aborted uploads. Inventory your dependency tree (e.g., npm ls multer and lockfiles) to find applications pinned to or resolving to 2.2.0, and prioritize any that use diskStorage on internet-reachable upload endpoints. Since no workarounds exist, as an interim measure monitor file descriptor counts and recycle Node processes that handle high upload-failure volumes until the patch is deployed.

openssl_encrypt before 1.4.9 executes untrusted third-party plugins with insufficient controls: the plugin signature policy defaulted to WARN, so an unsigned/unverifiable non-built-in plugin was compiled and executed in the host process at import time, before the runtime sandbox is installed. The only default gate was an incomplete, bypassable AST denylist. If a user is induced to load an attacker's plugin, this results in arbitrary code execution with the privileges of the user running openssl_encrypt. Fixed in 1.4.9 by defaulting the signature policy to ENFORCE for non-built-in plugins.

A maliciously crafted SVG file, when parsed through Autodesk 3ds Max, can force an Out-of-Bounds Read vulnerability. A malicious actor can leverage this vulnerability to cause a crash, read sensitive data, or execute arbitrary code in the context of the current process.

CVE-2026-78155 is a privilege escalation flaw in the OnGres StackGres Kubernetes operator in which a low-privileged tenant who owns a database can elevate to administrator privileges. The CVSS vector (AV:N/AC:L/PR:L/UI:N/S:C) indicates a network-based attack requiring only low privileges and no user interaction, with impact crossing the security scope boundary between tenant and operator. A successful attacker gains high confidentiality, integrity, and availability impact at the operator level, effectively administrative control beyond their own database. Any organization running a StackGres-managed PostgreSQL cluster where tenants are granted database ownership is potentially affected. A public reference is tracked in the project's GitLab issue tracker (work item 3177); EPSS is 0.3% (20th percentile) and the flaw is not in CISA KEV, so no confirmed in-the-wild exploitation is currently known.

Do: Monitor the vendor's advisory (GitLab work item 3177) and upgrade the StackGres operator as soon as a patched release is published, since no fixed version is stated in the source data. Until then, limit database-ownership grants to trusted tenants and restrict network access to the operator's management interfaces, and review operator audit logs for unexpected privilege changes.

There is an HTML injection vulnerability in Esri Portal for ArcGIS versions 11.5 and prior that allows a remote, highly priviliged attacker to insert arbitrary HTML into the Portal for ArcGIS Home application. Users working with ArcGIS Enterprise 11.1, 11.3, and 11.5 are encouraged to patch. All users are advised to upgrade to the latest long-term support release.
