CWE-99

Namespace injection in MongoDB C Driver (libmongoc) allows any caller-controlled database or collection name containing a '.' separator or NUL byte to redirect a MongoDB operation to an unintended resource. Applications that incorporate unsanitized user input into these name components are affected across all libmongoc versions prior to 2.5.1. No public exploit has been identified at time of analysis; the vendor released a validated fix in version 2.5.1.

Namespace injection in MongoDB Go Driver's Client.BulkWrite API allows an attacker who controls the database name argument to redirect bulk write operations to an unintended database and collection. When an application passes untrusted, user-supplied input directly as a database name, the driver fails to escape reserved MongoDB namespace separator characters before constructing the target namespace string. The impact is a high-integrity write misdirection - data is silently written to attacker-influenced storage targets. No public exploit and no CISA KEV listing exist at time of analysis.

Privilege escalation in Microsoft Exchange Server 2016, 2019, and Subscription Edition allows authenticated network attackers to gain elevated privileges through resource injection (CWE-99), earning a CVSS 8.8 High rating with total technical impact across confidentiality, integrity, and availability. Affected deployment tracks span Exchange 2016 CU23 (below 15.01.2507.072), Exchange 2019 CU14 and CU15, and Exchange SE RTM, with vendor patches confirmed available for all tracks. No public exploit code has been identified at time of analysis, and SSVC assessment reports no observed exploitation, though the authenticated-only barrier is easily bypassed via credential theft and the total SSVC technical impact classification warrants prompt action.

Resource identifier manipulation in macrozheng mall up to 1.0.3 allows authenticated remote attackers to access or affect return-application records belonging to other users by substituting arbitrary orderId values in POST requests to /returnApply/create. The flaw is classified as CWE-99 (Improper Control of Resource Identifiers), consistent with an Insecure Direct Object Reference (IDOR) pattern in the Portal Endpoint. A public exploit is available, and the vendor deleted the corresponding GitHub issue without comment, raising concerns about coordinated disclosure and patch status.

Workflow checkpoint endpoints in ComfyUI-Copilot up to 2.0.28 expose an insecure direct object reference (IDOR) flaw - the restore_workflow_checkpoint and update_workflow_ui handlers in conversation_api.py accept externally supplied version identifiers without verifying that the referenced checkpoint belongs to the requesting session, enabling an authenticated remote attacker to read workflow data owned by other sessions. The CVSS 4.0 score of 2.3 reflects limited confidentiality-only impact and high attack complexity (AC:H) due to the need to enumerate valid cross-session identifiers. A proof-of-concept is publicly available at GitHub issue #149; the upstream fix (PR #150) is pending acceptance and no patched release version has been confirmed.

Patient record exposure in medkey EHR (up to commit fc09b7ba9441ff590b72d428d5380834216b09ed) allows authenticated remote users to retrieve arbitrary patient records by manipulating the `id` parameter of the `actionGetPatientById` REST API endpoint - a textbook Insecure Direct Object Reference (BOLA/IDOR) flaw classified under CWE-99. A publicly available proof-of-concept exploit is hosted on GitHub (onyxglitch/Medkey-EHR-IDOR-PoC), materially lowering the exploitation barrier. The vendor did not respond to coordinated disclosure, leaving no confirmed patch and no official advisory for this rolling-release EHR system.

Insecure Direct Object Reference (IDOR) in SourceCodester Human Resource Management 1.0 allows authenticated remote attackers to read other employees' records by manipulating the `employeeid` parameter in `/detailview.php`. The vulnerability results in unauthorized disclosure of employee data across account boundaries, with no integrity or availability impact. A publicly available proof-of-concept exploit exists; no active exploitation has been confirmed by CISA KEV at time of analysis.

Insecure Direct Object Reference (IDOR) in code-projects Online Hospital Management System 1.0 allows a high-privileged remote attacker to manipulate the `delid` parameter in `viewdoctortimings.php`, resulting in unauthorized modification or deletion of doctor timing records beyond the attacker's intended access scope. The CVSS 4.0 score of 2.0 reflects the high privilege prerequisite (PR:H), low integrity impact (VI:L), and low availability impact (VA:L) to the vulnerable component. No public exploit identified at time of analysis as active exploitation - however, publicly available exploit code exists, documented in a GitHub proof-of-concept writeup.

Resource injection in the OUSL-GROUP-BrinaryBrains School Student Management System allows authenticated remote attackers to manipulate the param1 argument in the marks function of Parents.php, improperly controlling resource identifiers to access unauthorized academic records. The CVSS 4.0 score is 2.1, reflecting low-privilege authentication requirements (PR:L) and limited scope impact; a publicly available proof-of-concept exploit has been disclosed via a GitHub issue. No vendor patch exists - the project uses continuous delivery rolling releases and has not responded to the responsible disclosure report.

Resource injection in yashpokharna2555's StudentManagementSystem allows low-privileged remote attackers to manipulate the ID parameter in courseDel.php to control which course records are deleted or affected, resulting in unauthorized data integrity and availability impact. The flaw affects the specific git commit cb2f558ddf8d19396de0f92abf2d224d46a0a203 and exploit code is publicly available via a GitHub issue. No patch has been released, and the project maintainer has not responded to the disclosure.
