CVE-2026-81699 affects openssl_encrypt versions before 1.4.9, which fail to properly validate key derivation function (KDF) costs in crafted files. Attackers can supply malicious files containing excessive KDF parameters to trigger unbounded memory and CPU exhaustion. The vulnerability is exploitable during pre-authentication processing, meaning no valid credentials are required to launch the attack. Successful exploitation can cause the affected process to crash or become unresponsive. This represents a Denial of Service (DoS) risk that can be triggered remotely before any password verification occurs. The fix is available in openssl_encrypt version 1.4.9 and later.
Bekijk origineel advisory →OpenRemote versions before 1.28.0 contain a cross-realm information disclosure vulnerability in the Notification REST API. The flaw allows per-realm tenant administrators with read:admin credentials to access sent notifications from all tenants, not just their own realm. Exploitation requires only a zero-parameter GET request to the notification endpoint, making it trivially easy to abuse. Sensitive notification metadata and message content from all realms can be retrieved by an attacker with access to any single realm. The vulnerability has been addressed in OpenRemote version 1.28.0. This represents a significant access control failure in a multi-tenant architecture. The issue is documented in both the NVD and GitHub Security Advisories. Organizations running OpenRemote in multi-tenant deployments are particularly at risk. The vulnerability could expose confidential communications between administrators and users across all tenants.

Bekijk origineel advisory →CVE-2026-81335 affects Baserow versions prior to 2.3.1, exposing a critical authorization bypass in the Application Builder's data source dispatch mechanism. The dispatch and record-name API views are configured with a permissive class that allows any caller, including unauthenticated requests, to reach the handler. The DataSourceService.dispatch_data_sources method calls check_multiple_permissions but never evaluates or stores the denial mapping it returns, allowing execution to continue regardless of permission outcome. As a result, the data source is dispatched using the integration's own credentials, leaking rows and fields to unauthenticated callers. Data source identifiers are small integers, making them trivially enumerable and increasing the risk of mass data exposure. The fix in version 2.3.1 passes the raise_exception flag to the permission check, ensuring denials halt execution. This vulnerability enables unauthenticated data exfiltration from any Baserow Application Builder data source. Organizations using Baserow should upgrade to version 2.3.1 immediately.
Bekijk origineel advisory →CVE-2026-77438 affects Trilium, an open-source hierarchical note-taking application, in versions up to and including 0.103.0. The public share-search endpoint fails to enforce per-note shareCredentials and shareHiddenFromTree access controls. An unauthenticated attacker can exploit this flaw to read titles, tree paths, and full content of password-protected shared notes. The endpoint only authorizes the ancestor note in the request and then performs a full-text search across the entire published subtree without re-checking individual note permissions. This allows an attacker to use the endpoint as a boolean oracle to confirm arbitrary substrings and reconstruct protected note contents. The vulnerability enables enumeration of hidden notes and bypass of share password protections. No authentication is required to exploit this issue. The vulnerability has been fixed in Trilium version 0.104.0.
Bekijk origineel advisory →CVE-2026-81093 describes a Server-Side Request Forgery (SSRF) vulnerability in the Apify MCP Server's get-html-skeleton tool. The tool accepted caller-supplied URLs and only validated their syntax (http/https scheme and parseable format) without inspecting the hostname or resolved IP address. This allowed loopback, link-local, and private IP ranges to pass validation, including cloud provider instance metadata endpoints (e.g., 169.254.169.254). Any caller of the MCP server could exploit this to make the server fetch internal-only endpoints and return the response, potentially exposing sensitive instance credentials and internal services. The vulnerability resided in src/tools/common/get_html_skeleton.ts using the isValidHttpUrl function from src/utils/generic.ts. The fix in version 0.9.12 removes the vulnerable tool entirely rather than patching the URL validation logic.
Bekijk origineel advisory →openssl_encrypt versions prior to 1.4.9 contain a critical signature verification vulnerability in the gpg_runner.verify_detached function. The flaw arises from only checking the VALIDSIG status while ignoring REVKEYSIG, EXPKEYSIG statuses and GPG exit codes. This oversight allows attackers who possess revoked or expired signing keys to bypass signature verification entirely. Successful exploitation enables the execution of malicious plugins within the host process. The vulnerability poses a significant risk as it undermines the integrity of the plugin loading mechanism. Users are advised to upgrade to version 1.4.9 or later to remediate the issue.
