CWE-639
Weakness AllowedAuthorization Bypass Through User-Controlled Key
Abstraction: Base · Status: Incomplete
The system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data.
It is likely that an attacker would have to be an authenticated user in the system. However, the authorization process would not properly check the data access operation to ensure that the authenticated user performing the operation has sufficient entitlements to perform the requested data access, hence bypassing any other authorization checks present in the system.
For example, attackers can look at places where user specific data is retrieved (e.g. search screens) and determine whether the key for the item being looked up is controllable externally. The key may be a hidden field in the HTML form field, might be passed as a URL parameter or as an unencrypted cookie variable, then in each of these cases it will be possible to tamper with the key value.
Mapping guidance
This CWE entry is at the Base level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.
Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.
Relationships and members
Modes of introduction
REALIZATION: This weakness is caused during implementation of an architectural security tactic.
Retrieval of a user record occurs in the system based on some key value that is under user control. The key would typically identify a user-related record stored in the system and would be used to lookup that record for presentation to the user.
One manifestation of this weakness is when a system uses sequential or otherwise easily-guessable session IDs that would allow one user to easily switch to another user's session and read/modify their data.
Detection methods
Automated Static Analysis
Automated static analysis, commonly referred to as Static Application Security Testing (SAST), can find some instances of this weakness by analyzing source code (or binary/compiled code) without having to execute it. Typically, this is done by building a model of data flow and control flow, then searching for potentially-vulnerable patterns that connect "sources" (origins of input) with "sinks" (destinations where the data interacts with external components, a lower layer such as the OS, etc.)
Effectiveness: High
Notes
Maintenance
As of CWE 4.20, the relationship between IDOR and BOLA needs to be investigated more closely, including research into how these terms are used in the industry. The CWE team suspects that IDOR can be a part of BOLA, but BOLA expands on the weakness inherent to IDOR in that it is not only about objects that are being directly referenced.

GHSA-XC8Q-RH3X-H9M3
Vulnerability from github – Published: 2026-03-13 21:31 – Updated: 2026-03-13 21:31The Formidable Forms plugin for WordPress is vulnerable to an authorization bypass through user-controlled key in all versions up to, and including, 6.28. This is due to the frm_strp_amount AJAX handler (update_intent_ajax) overwriting the global $_POST data with attacker-controlled JSON input and then using those values to recalculate payment amounts via field shortcode resolution in generate_false_entry(). The handler relies on a nonce that is publicly exposed in the page's JavaScript (frm_stripe_vars.nonce), which provides CSRF protection but not authorization. This makes it possible for unauthenticated attackers to manipulate PaymentIntent amounts before payment completion on forms using dynamic pricing with field shortcodes, effectively paying a reduced amount for goods or services.

This is due to the plugin not properly verifying that a user is authorized to perform an action when processing attacker-supplied Stripe PaymentIntent identifiers in the public payment flow.

Vulnerability from github – Published: 2026-02-26 22:13 – Updated: 2026-04-15 20:42Summary
RepetitionsConfigViewSet and MaxRepetitionsConfigViewSet return all users' repetition config data because their get_queryset() calls .all() instead of filtering by the authenticated user. Any registered user can enumerate every other user's workout structure.
Details
wger/manager/api/views.py:499 and :518:
# VULNERABLE
class RepetitionsConfigViewSet(viewsets.ModelViewSet):
def get_queryset(self):
return RepetitionsConfig.objects.all()
class MaxRepetitionsConfigViewSet(viewsets.ModelViewSet):
def get_queryset(self):
return MaxRepetitionsConfig.objects.all()
Every sibling viewset in the same file correctly filters by user. For example, WeightConfigViewSet at line 459:
# CORRECT — how it should work
def get_queryset(self):
return WeightConfig.objects.filter(
slot_entry__slot__day__routine__user=self.request.user
)
The same user filter is present on SetsConfig, RestConfig, RiRConfig, and their Max variants — only RepetitionsConfig and MaxRepetitionsConfig are missing it.
PoC
import requests
BASE = "http://localhost"
headers = {"Authorization": "Token YOUR_TOKEN"} # any registered user
r = requests.get(f"{BASE}/api/v2/repetitions-config/", headers=headers)
print(r.json()) # returns ALL users' repetition configs, not just your own
r = requests.get(f"{BASE}/api/v2/max-repetitions-config/", headers=headers)
print(r.json()) # same — all users' max repetition configs
Registration is open by default. Sequential IDs allow full enumeration.
Impact
Any authenticated user can read other users' repetition and max-repetitions configs, exposing workout structure (slot entry IDs, iteration values, operations, step counts, repeat flags, requirements JSON). This is a broken object-level authorization (BOLA/IDOR) vulnerability — the same class of issue as OWASP API1.
Fix: Add the same user filter used by every other config viewset:
def get_queryset(self):
return RepetitionsConfig.objects.filter(
slot_entry__slot__day__routine__user=self.request.user
)

Vulnerability from github – Published: 2025-02-28 09:30 – Updated: 2026-04-08 18:33The Ultra Addons Lite for Elementor plugin for WordPress is vulnerable to Information Exposure in all versions up to, and including, 1.1.8 via the 'ut_elementor' shortcode due to insufficient restrictions on which posts can be included. This makes it possible for authenticated attackers, with Contributor-level access and above, to extract data from password protected, private, or draft posts that they should not have access to.

Mitigation
For each and every data access, ensure that the user has sufficient privilege to access the record that is being requested.
Mitigation
Make sure that the key that is used in the lookup of a specific user's record is not controllable externally by the user or that any tampering can be detected.
Mitigation
Use encryption in order to make it more difficult to guess other legitimate values of the key or associate a digital signature with the key so that the server can verify that there has been no tampering.
