Vulnerability from github – Published: 2026-05-05 09:31 – Updated: 2026-05-05 09:31The Forminator plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.52.0. 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. This makes it possible for unauthenticated attackers to submit high-value paid forms as completed by reusing a previously succeeded low-value Stripe PaymentIntent, resulting in underpayment/payment bypass conditions.

GHSA-XF68-8HJW-7MPM
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
)

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.
