Descripción técnica

Joomla Extension - j2commerce.com - Unescaped request data reflected into PayPal notify redirect in J2Store 1.0.0-3.3.2, 4.0.0-4.0.22, 4.1.0-4.1.7 - A crafted link to the paypal notify endpoint, if followed by a victim's browser (or an automated system that fetches it), causes the resulting redirect to `com_j2store`'s checkout controller to carry attacker-chosen query parameters instead of only the intended `view=checkout&task=confirmPayment&orderpayment_type=...&paction=process` set — parameter injection/smuggling into that follow-up request. This requires a victim to load the crafted link (`UI:R`/`UI:P`); it does not by itself grant an unauthenticated attacker anything they could not already obtain by requesting the target `com_j2store` URL directly with their own parameters.

——8Joomla Extension - j2commerce.com - Predictable/forgeable order access token in J2Store 1.0.0-3.3.2, 4.0.0-4.0.22, 4.1.0-4.1.7 - Anyone who obtains the site's Joomla `secret` can compute a valid access token for *any* order on the site without ever having placed one, gaining guest access to that order's details and any purchased digital downloads. Because the token is never rotated, this exposure persists indefinitely even after the underlying secret-disclosure vector is patched, unless the Joomla secret itself is also rotated. The attack complexity (`AC:H`) is high because it depends on the secret already being known through a separate vector; it is not directly exploitable by an anonymous visitor with no other foothold.48d CVE-2026-735766.3 MED

——8In Zimbra Collaboration (ZCS) before 10.1.17, weak cryptographic key generation vulnerability exists in the OnlyOffice integration. The zimbraDocumentEditingJwtSecret is generated using an insecure random number generator, resulting in insufficient entropy. An attacker who obtains a JWT signed with the generated secret may be able to recover the JWT signing secret through offline brute-force, potentially enabling JWT forgery.67d CVE-2026-57869—

——9Broken object-level access controls and the use of a deterministic pattern during random ID generation in MicroRealEstate allows attackers to access documents uploaded by landlords or tenants without authorization. This issue affects MicroRealEstate: through 1.0.0-alpha3.119d CVE-2026-64206.3 MED

——1A flaw was found in Keylime. An attacker with root access on an enrolled monitored machine, where the Keylime agent runs, can exploit a vulnerability in the Keylime verifier. The verifier uses a hardcoded challenge nonce for Trusted Platform Module (TPM) quote attestation instead of a cryptographically random value. This allows the attacker to stockpile valid TPM quotes and replay them to evade detection after compromising the system. This issue affects only the push model deployment.8d CVE-2026-260187.5 ALT

——21CoreDNS is a DNS server that chains plugins. Prior to version 1.14.2, a denial of service vulnerability exists in CoreDNS's loop detection plugin that allows an attacker to crash the DNS server by sending specially crafted DNS queries. The vulnerability stems from the use of a predictable pseudo-random number generator (PRNG) for generating a secret query name, combined with a fatal error handler that terminates the entire process. This issue has been patched in version 1.14.2.112d
