| The Booking Package WordPress plugin before 1.7.33 does not restrict who can trigger its booking verification-code emails nor bind the recipient to server-side state, allowing unauthenticated users to make the site send templated verification-code emails to arbitrary recipients. |
| The Royal Addons for Elementor WordPress plugin before 1.7.1070 does not scope a contact form's email delivery configuration to the form's own document or owner, instead storing it in a site-global namespace keyed only on a non-secret, author-chosen identifier that is exposed in public page source, allowing users with the Author role or above to overwrite another user's form configuration and have that form's submissions delivered to an attacker-controlled address. |
| The PayPlug for WooCommerce (Official) WordPress plugin before 3.1.1 does not verify that the requester owns the WooCommerce order named in a payment request, allowing unauthenticated users to disclose another customer's order key and cancel their unpaid guest order. |
| In the Linux kernel, the following vulnerability has been resolved:
sched/core: Call wakeup_preempt() for queued tasks during class change
Paul reported recent RCU changes exposed a lost resched where CPU idles
with a rcutorture thread waiting while being completely runnable.
Dumping the rq state at the time of idling with runnable tasks showed
the following:
rq->next_class = &fair_sched_class
rq->nr_running = 1
rq->cfs.h_nr_queued = 0
rq->rt.rt_nr_running = 1
Although the waiting task was an RT task, "rq->next_class" did not point
to rt_sched_class and was stuck at the lower priority fair_sched_class.
Inspecting sched_change_end() revealed the following race with
__sched_setscheduler() for queued, but non-running tasks:
CPU0 CPU1
==== ====
__schedule()
/*
* rq->donor is a fair task that blocks.
* rq->next_class = &fair_sched_class
*/
rq_lock(rq0)
pick_next_task()
/* nr_running = 0 */
pick_task_fair()
sched_balance_newidle()
raw_spin_rq_unlock(rq0)
rq_lock(rq0)
activate_task(rq0, p)
/* p is a fair task */
rq0->nr_running++;
rq0->cfs.h_nr_queued++;
wakeup_preempt(rq, p)
rq->next_class = &fair_sched_class
resched_curr()
rq_unlock(rq0)
__sched_setscheduler(p)
/* p is moved to SCHED_RR */
task_rq_lock(p)
sched_change_begin()
rq0->cfs.h_nr_queued--;
rq0->rt.rt_nr_running++;
sched_change_end()
/*
* p->on_rq = 1 (ctx->queued)
* but p is not rq->donor
* (!ctx->running) hence
* resched_curr() is and
* rq->next_class upgrade is
* skipped.
*/
task_rq_unlock()
raw_spin_rq_lock(rq0)
/*
* rq->nr_running = 1
* rq->cfs.h_nr_queued = 0
* rq->rt.rt_nr_running = 1
* rq->next_class = &fair_sched_class
*/
if (rq->cfs.h_nr_queued && ...)
/* Above is false */
if (rq_modified_above(this_rq, &fair_sched_class))
/* Also false since rq->next_class is still fair */
/*
* sched_balance_newidle() is considered to
* have failed to pull any fair tasks and no
* other wakeups were detected.
*/
return NULL; /* pick_task_fair() */
pick_task_idle()
return rq->idle;
next = rq->idle;
/* Preemption indicators are lost */
clear_tsk_need_resched(prev);
clear_preempt_need_resched();
rq->curr = rq->idle;
!!! rq->idle switches in with rq->running == 1 but !need_resched() !!!
In simple words, enqueue, followed by a class change of the newly queued
task goes unnoticed in rq->next_class indicator and
sched_balance_newidle() sees no fair task, nor any higher priority task
enqueued.
The above sequence will lead to CPU idling with a runnable task on the
CPU.
Call wakeup_preempt() for ctx->queued cases in sched_change_end() to
re-evaluate rq->next_class after class change (ENQUEUE_CLASS) and set
the NEED_RESCHED indicator accordingly.
Newidle balance will correctly see an enqueue of a higher priority
