CVE Vulnerability Catalog

A missing authorization flaw in PostgreSQL DDL commands allows an object creator to cause denial of service against ALTER and DROP of a type by creating a dependency on it. Many DDL operations checked privileges, but assigning a range subtype and referencing the type from an SQL expression did not. Versions before PostgreSQL 18.5, 17.11, 16.15, 15.19, and 14.24 are affected.

A buffer over-read vulnerability was found in PostgreSQL's ascii() SQL function, allowing a user to disclose up to 3 bytes after the end of a specific allocation via a crafted text value. This is the same class of defect fixed in CVE-2026-2006, though this instance has less impact. Versions before PostgreSQL 18.5, 17.11, 16.15, 15.19, and 14.24 are affected.

Improper enforcement of message integrity in PostgreSQL GSSAPI support allows a user to negotiate GSSAPI contrary to pg_hba.conf rules via initial direct TLS connection. Despite a pg_hba.conf that appears to require GSSAPI, the connection may exchange data over TLS encryption alone. If TLS settings are more permissive than GSS settings, the connection may continue with lesser protection. Within major versions 17-18, minor versions before PostgreSQL 18.5 and 17.11 are affected; versions before PostgreSQL 17 are unaffected.

A buffer over-read vulnerability was found in PostgreSQL's pg_trgm index picksplit function, which reads past the end of a heap buffer. This might allow a table maintainer to infer limited memory values via the lossy signal of index split choices. Versions before PostgreSQL 18.5, 17.11, 16.15, 15.19, and 14.24 are affected.

An observable response discrepancy in PostgreSQL SCRAM authentication allows an unauthenticated user to test the existence of a user by observing the SCRAM iteration count. This requires the probed user to have a non-default scram_iterations count, because the authentication challenge for a nonexistent user reports the default. Within major versions 16-18, minor versions before PostgreSQL 18.5, 17.11, and 16.15 are affected; versions before PostgreSQL 16 are unaffected.

Incomplete tracking in PostgreSQL of changes to role membership, role attributes, and database ownership allows a query to continue using cached row-level security policies after those changes require a different policy, via plan reuse. Stale policies continue until some other event invalidates the cache or connection termination ends the session. This permits a user to complete reads and modifications that were recently permitted but now forbidden. An attacker must tailor an attack to a particular application's pattern of privilege removal and role-specific row security policies. Versions before PostgreSQL 18.5, 17.11, 16.15, 15.19, and 14.24 are affected.

Cleartext storage in PostgreSQL pgcrypto disabled ciphers allows a user to recover cleartext via direct observation of the faulty ciphertext. The OpenSSL version and configuration determine the disabled ciphers. If the application accepts encrypted data as input, decryption will succeed even with the wrong key, losing the modest protection from the Modification Detection Code (MDC). Affected functions include pgp_sym_encrypt, pgp_sym_decrypt, pgp_pub_encrypt, pgp_pub_decrypt, and their bytea variants. Versions before PostgreSQL 18.5, 17.11, 16.15, 15.19, and 14.24 are affected.

HCL AION is affected by a vulnerability where the shared storage used by product components is architected without sufficient access separation. Processes sharing the storage may be able to access or modify files beyond their intended scope, potentially resulting in unintended behavior or security impact under certain conditions.

Serendipity versions >= 2.3.5 and <= 2.6.0 contain a reflected cross-site scripting vulnerability in the search clean-URL route (/search/<term>). In include/functions_routing.inc.php serveSearch(), the sanitisation pipeline runs urldecode() after HTML-encoding, so a single URL-encoded HTML payload survives strip_tags() and htmlspecialchars() and is then decoded back into live HTML in the page. A crafted search link can execute arbitrary JavaScript in the victim's browser. Fixed in 2.6.1.

JupyterLab (pip package 'jupyterlab') versions >=4.1.0,<=4.5.9 and >=4.6.0,<=4.6.1 contain a plugin manager lock-rule enforcement bypass. Two server-side enforcement gaps allow an authenticated user to circumvent administrator lock rules by making direct requests to the /lab/api/plugins endpoint, enabling or disabling plugins that were locked — including child plugins of multi-plugin extensions and plugins locked via the 'lock all' mechanism. This can impact data integrity and bypass hardening or restrictions (e.g., download/upload limits) implemented through locked plugins. Fixed in versions 4.6.2 and 4.5.10.

GitPython before 3.1.56 contains an argument injection vulnerability in the Commit.count() method, which forwards keyword arguments to 'git rev-list' without the check_unsafe_options guard present in the sibling iter_items method. An attacker who can control options passed to Commit.count (e.g., via an application that forwards a user-supplied options dict) can supply output=<path>, causing 'git rev-list --output=<path>' to open and truncate the target file to zero bytes before revision parsing. This allows destruction/blanking of an arbitrary file at the process's privilege level (no content control, 0-byte truncation).

GitPython before 3.1.57 contains an incomplete denylist in the unsafe_git_archive_options guard that omits --add-file and --add-virtual-file options. Attackers can supply these options to Repo.archive() to read arbitrary files from the filesystem and include them in the returned archive.

OpenRemote notification deletion endpoints fail to enforce realm boundaries, allowing any realm administrator to delete notifications belonging to other realms. Attackers with write:admin role in one realm can send DELETE requests to remove notifications from the master realm or other tenants without authorization checks.

File Browser versions from 2.50.0 through 2.63.21 fail to validate JWT expiration when proxy authentication is configured with a non-default logout page. Attackers with a previously valid token can access protected routes and administrative endpoints indefinitely, and exchange expired tokens for fresh ones via the renewal endpoint.

SiYuan before v3.7.4 contains an information disclosure vulnerability in the local storage filter that returns the administrator's entire storage map with only three keys sanitized. Unauthenticated attackers or publish readers can retrieve closed-tab history, search keywords, private document identifiers, and expanded folder paths by calling the getLocalStorage endpoint.

SiYuan versions before v3.7.4 contain an information disclosure vulnerability in the getBookmarkLabels endpoint that returns all bookmark labels in the workspace without publish-access filtering. Anonymous readers and publish-mode readers can obtain the complete bookmark vocabulary across the workspace, disclosing subject matter and organizational information from inaccessible documents.

SiYuan versions before v3.7.4 contain an information disclosure vulnerability in the /api/storage/getOutlineStorage endpoint that performs no authorization checks. Attackers can retrieve outline state including heading identifiers for any document by supplying its identifier, even for documents forbidden to the requester.

SiYuan versions before v3.7.4 contain an information disclosure vulnerability in the /api/block/getRefIDs endpoint that fails to check password-protected document tiers. Unauthenticated readers can discover that password-protected documents reference specific blocks and obtain block identifiers without entering the document password.

SiYuan before version 3.7.4 contains a path traversal vulnerability in the getUniqueFilename endpoint that allows anonymous readers to probe filesystem existence without validation or confinement. Attackers can supply arbitrary absolute paths to determine whether files and directories exist on the host, enabling reconnaissance of the filesystem layout and installed software.

Flowise before 3.1.3 contains an incomplete credential redaction vulnerability in the GET /api/v1/credentials/:id endpoint that returns decrypted secrets in plaintext. Authenticated users with credentials:view permission can retrieve sensitive data including database connection URLs with embedded passwords, cloud service account JSON with private keys, and API keys by calling this endpoint.
