Exploitation Conditions

Exploitation requires an authenticated merchant account that holds the ENT_DIVISION_RECEIVER_DELETE entitlement, plus ownership of a division receiver group whose id value collides with the target victim's receiver id - the ownership check is performed against the wrong column (receiver-group ownership) rather than the receiver record itself. The practical limiting factors are significant: the attacker must already be a provisioned merchant with the specific delete permission, and must engineer or find an id match between their owned group and the victim's receiver, which is why the CVSS carries AC:H and AT:P. Impact is confined to deletion of profit-sharing receiver records (integrity/availability), with no read access to victim data.

Impact

This is a genuinely low-priority issue, and the signals are consistent in saying so. The CVSS 4.0 base score is 2.3 (Low), driven by AV:N but offset by AC:H, AT:P (a specific attack requirement), PR:L (authenticated merchant), and only partial integrity/availability impact (VI:L/VA:L) with no confidentiality impact (VC:N). The vector aligns well with the description: exploitation is not trivially repeatable because it depends on an attacker-controlled receiver-group id coincidentally matching a victim's receiver id, which is why AC:H and AT:P are appropriate. No EPSS score, KEV listing, or POC indicator is provided in the input, so there is no public exploit identified at time of analysis and no evidence of active exploitation. There are no conflicting signals here - a low CVSS correctly reflects a narrow, authenticated, conditions-dependent authorization flaw rather than a widely weaponizable bug. The main caveat is data completeness: EPSS and POC status are simply absent from the feed (absence is not evidence either way), and the fix/patch status is not stated.

Exploit ScenarioDerived

A legitimate but malicious merchant user with the ENT_DIVISION_RECEIVER_DELETE permission creates or identifies a profit-sharing receiver group under their own account whose id happens to match the receiver id belonging to a different merchant. They then invoke the division-receiver delete API, and because the ownership check validates the wrong column, the platform deletes the victim merchant's profit-sharing receiver, disrupting that merchant's payout configuration. No public exploit code is identified in the provided data, but a technical write-up describing the flaw is referenced.

AnalysisAIv1 – Oct 16, 2026

An insecure direct object reference in Jeepay through version 3.2.9 lets an authenticated merchant user who holds the ENT_DIVISION_RECEIVER_DELETE entitlement delete profit-sharing (division) receiver records belonging to a different merchant. The flaw stems from the delete handler validating ownership against the wrong column - the caller's receiver-group ownership rather than the receiver record itself - so an attacker who owns a group whose id collides with a victim's receiver id can pass the check and remove that receiver. Exploitation requires a provisioned merchant account with the specific delete permission plus an id collision (reflected in the assessed CVSS as AC:H/AT:P), and impact is limited to deletion of receiver records with no read access to victim data; no public exploit code has been identified at time of analysis, and the issue is assessed as genuinely low priority.

RemediationAI

No vendor-released patch was identified at time of analysis; the referenced GitHub link points to the vulnerable V3.2.9 source rather than a fix commit, so administrators should track the Jeepay project and the VulnCheck advisory (https://www.vulncheck.com/advisories/jeepay-through-3.2.9-idor-via-delete-api-divisionreceivers-recordid) for an upstream fix and apply it as soon as a patched release is published. Until then, the most effective compensating control is to audit and restrict the ENT_DIVISION_RECEIVER_DELETE entitlement so it is granted only to a minimal set of trusted merchant roles - this does not remove the flaw but sharply limits the pool of accounts that can reach the vulnerable handler. Secondary mitigations include temporarily disabling or blocking the division-receiver delete API (or placing it behind an out-of-band confirmation/approval step), which prevents exploitation but breaks legitimate receiver-management workflows, and adding server-side logging/alerting on cross-merchant delete attempts against MchDivisionReceiverController so that any abuse is detected; a code-level fix should replace the receiver-group ownership predicate with a check against the receiver record's own merchant/owner column. Each of these controls reduces reachability or detects abuse without eliminating the underlying wrong-column authorization defect, so they should be treated as temporary measures pending an official patch.

Technical ContextAI · show details

Jeepay is an open-source payment system; the affected code resides in the merchant-facing division (profit-sharing) controller, jeepay-merchant/src/main/java/com/jeepu/jeepay/mch/ctrl/division/MchDivisionReceiverController.java (lines 250-259 at tag V3.2.9), which handles deletion of division receiver records. The root cause is CWE-639, Authorization Bypass Through User-Controlled Key: the access-control check for the DELETE operation is performed against a receiver-group ownership predicate instead of the receiver record's own merchant/owner association, meaning the request-supplied record id is used against the wrong object. As a result, when an attacker's owned receiver group shares an id value with the victim's receiver record, the authorization check is satisfied incorrectly. The CPE cpe:2.3:a:jeequan:jeepay:*:*:*:*:*:*:*:* indicates all versions through the 3.2.9 release are in scope, and the flaw is reachable over the network from the merchant application with only a low-privileged authenticated session (CVSS:4.0 vector AV:N/AC:H/AT:P/PR:L/UI:N) and no user interaction.

DescriptionCVE.org

Jeepay through 3.2.9 contains an insecure direct object reference vulnerability that allows authenticated merchant users to delete other merchants' division receivers by exploiting an ownership check on the wrong column. Attackers holding ENT_DIVISION_RECEIVER_DELETE who own a receiver group whose id matches a victim's receiver id can delete the victim's profit-sharing receiver.
