Adobe ColdFusion/Campaign APSB26-68/69

Adobe Campaign Classic APSB26-120 — three more unauthenticated CVSS 10.0 code-execution flaws, and last week's build 9398 is the version they affect

Five days after Adobe fixed two critical unauthenticated flaws in Campaign Classic with build 9398 — APSB26-114, dated 2026-07-29, also a Priority 1 update (Adobe PSIRT, 2026-07-29) — it published a second bulletin whose affected range includes build 9398. APSB26-120, dated 2026-08-03, covers seven vulnerabilities in the on-premise campaign-management platform and records the affected versions as "ACC v7: 7.4.3 build 9398 and earlier", fixed in ACC v7 7.4.3 build 9399, at Adobe's highest priority rating of 1 (Adobe PSIRT, 2026-08-03). Any operator who treated last week's build as the end state — which is what the previous advisory called for — is still carrying every flaw below.

Three of the seven need no authentication and no user interaction, each scored CVSS 10.0 with changed scope (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H), and each independently sufficient for arbitrary code execution per Adobe's own impact column: CVE-2026-48331, a server-side request forgery (CWE-918); CVE-2026-48323, improper neutralization of special elements used in a template engine (CWE-1336); and CVE-2026-48330, a SQL injection (CWE-89). Four more carry a precondition: CVE-2026-48326 (CVSS 9.9) is a second SQL injection reaching code execution but requiring low privileges; CVE-2026-48333 (CVSS 9.8) is an incorrect-authorization flaw (CWE-863) giving unauthenticated privilege escalation; CVE-2026-48317 (CVSS 9.6) is an eval injection (CWE-95) needing low privileges; and CVE-2026-48399 (CVSS 7.5) is a violation of secure design principles (CWE-657) yielding a security-feature bypass. Adobe rates all seven Critical and states that it "is not aware of any exploits in the wild for any of the issues addressed in these updates" (Adobe PSIRT, 2026-08-03). NCSC-NL relayed the bulletin on 2026-08-06 and is explicit that it is not an update of its own earlier Campaign Classic advisory but a separate set of newly found vulnerabilities (NCSC-NL, 2026-08-06).

Exposure is a question of who runs their own instance: the bulletin "applies only to fully on-premise deployments of Adobe Campaign Classic and to the on-premise components of hybrid deployments", with Adobe-hosted instances already remediated and needing no customer action (Adobe PSIRT, 2026-08-03). This is the third distinct wave of critical unauthenticated code-execution-class disclosures against this product line since late June (Adobe PSIRT, 2026-07-29), each at Adobe's top priority, which is itself the planning signal — a platform producing pre-auth CVSS-10.0 flaws on a roughly weekly cadence is one to move off the public internet rather than one to keep patching in place. Detection concepts, telemetry class first: with no public proof-of-concept and no reported exploitation, version state is the only reliable check, so inventory on-premise ACC instances against build 9399 rather than waiting for exploitation telemetry; where the application server's outbound traffic is logged, unexpected egress initiated by the ACC process is the observable class the SSRF would produce, and unexpected child processes spawned by the web or template-rendering service is what the template-injection and eval-injection paths would produce. Both are behavioural classes derived from the flaw types Adobe names, not from any reported intrusion — no cited source describes an actual attack against these CVEs, so nothing here should be read as a hunt for known activity. One bookkeeping change worth noting for anyone who tracks Adobe CVE counts: the bulletin states that effective 2026-08-11, Adobe may assign a single CVE identifier to internally discovered vulnerabilities sharing a severity rating and CWE category when a release includes systemic fixes, so future counts will understate flaw counts relative to this one.

Confirmed in-the-wild exploitation of internet-facing enterprise software converged this week — ColdFusion, Citrix NetScaler and Gitea all moved from 'at risk' to 'under attack'

If you did nothing this week: three classes of internet-facing enterprise software you likely have somewhere in the estate moved from theoretical risk to confirmed exploitation. An unpatched, exposed ColdFusion, Citrix NetScaler Gateway or Gitea instance should be handled as an incident, not a maintenance ticket — and for NetScaler, applying the patch does not evict an attacker who already has your session tokens.

The week's exploitation signal converged on the perimeter. Adobe ColdFusion CVE-2026-48282 — one of the six unauthenticated CVSS 10.0 RCEs Adobe patched on 1 July, and exactly the item last week's outlook flagged as awaiting weaponisation — was confirmed exploited in the wild and added to CISA KEV on 7 July; KEVIntel reported catching exploitation "within under two hours of CVE-2026-48282 public details being released" against its honeypots (BleepingComputer, 2026-07-08). Citrix NetScaler saw the most operationally consequential development: Huntress reconstructed a mechanically identical intrusion chain across at least six unrelated organisations, run by an initial-access broker (Sophos: STAC3725) that steals pre-auth session tokens via CitrixBleed 2 (CVE-2025-5777) — "sift[ing] through the heap fragments for valid session tokens of someone who is currently logged in" (Huntress, 2026-07-10) — then escalating via a registry-symlink privilege-escalation tool to SYSTEM, persisting with ScreenConnect/Zoho Assist, and in the most progressed case deploying DragonForce ransomware. Because the stolen tokens survive patching, remediation requires terminating live sessions as well. Finally, NCSC-CH escalated the Gitea Docker reverse-proxy authentication bypass (CVE-2026-20896) — full unauthenticated admin control "via a single custom HTTP header" — to "Actively Exploited, Proof of Concept Available" (NCSC-CH Cyber Security Hub, 2026-07-10). A fourth strand — Langflow's cross-tenant IDOR (CVE-2026-55255) chained with pre-auth RCE, first exploited 25 June and now KEV-listed (Sysdig, 2026-07-08) — reinforces the same lesson: exploitation, not CVSS, is what set this week's priorities.

CVE-2026-48282 — Adobe ColdFusion path-traversal RCE now actively exploited and CISA KEV-listed

UPDATE · originally covered CVE-2026-48276, -48277, -48281, -48282, -48283, -48316 — Adobe ColdFusion: six CVSS 10.0 unauthenticated RCE paths (2026-07-02)

The 2026-07-02 entry covered Adobe's APSB26-68/69 cluster — six CVSS 10.0 unauthenticated ColdFusion RCE paths plus a Campaign Classic flaw — while Adobe stated it was "not aware of any exploits in the wild." That status has now changed for one member of the cluster. CVE-2026-48282, the CWE-22 path-traversal path, is the first of the six confirmed exploited: KEVIntel reported in-the-wild exploitation captured across its honeypot network within under two hours of the technical details going public (BleepingComputer, 2026-07-06). CISA added CVE-2026-48282 to its Known Exploited Vulnerabilities catalog on 7 July (CISA KEV, 2026-07-07), and BleepingComputer reports Shadowserver telemetry putting internet-exposed ColdFusion instances at roughly 800 (BleepingComputer, 2026-07-08). The remaining five cluster CVEs (CVE-2026-48276/-48277/-48281/-48283/-48316) remain unconfirmed for exploitation as of this run — but the sub-two-hour weaponisation of the first path is the operational signal that the whole cluster is being probed.
